• Long waves are less powerful, short are more powerful.


• Which waves are more powerful, Radiowaves or Gamma Rays?

• Which waves are more powerful, Ultraviolet or Infrared?

• Which color is more powerful,• Red or Violet?

Waves of the electromagnetic spectrum travel at the speed of light. 186,000 miles per second or 300,000 kilometers per second in a vacuum.Visible light measured in lumens.All others are measured in radiation.


• All energy waves have an electric and magnetic field to them.


Radiation when it hits something can be…AbsorbedReflectedScattered

Diffraction, RefractionTransmitted


Temperature of an object relates to the amount of radiation released.-


Temperature of an object relates to the amount of radiation released.The hotter, the more radiation

released.


Radiowaves: Longest wave in the spectrum.Size of a football field. Not very

powerful.


• The difference between AM and FM is the frequency of the wave.


• Which radio has the higher frequency, AM or FM radio?




Frequency: The number of occurrences within a given time period.

• Which radio has the higher frequency, AM or FM radio? Answer: FM


• What does AM and FM and stand for?




AM = Amplitude Modulation



AM = Amplitude Modulation

FM = Frequency Modulation

• They have a number of important uses for communication.


• They have a number of important uses for communication.– Various waves in the EM spectrum have

different behaviors and therefore uses as they interact with matter.

• What is Radio Direction and Ranging?


• Answer! Radar


• How RADAR works.– Radio waves bounce off of an object and

return, size and distance is then obtained.


• Unless the radio wave is deflected in a way that won’t make it back to the RADAR device.




This would be bad because the radar would detect the bomber.



This is what actually happens. The bomber is undetected.

• What are the advantages of using a digital message such as email or cell phone over handwritten mail?


• Advantages?– Message travels at the speed of light.

• 299,792,458 m / s

– Stored and organized on a computer.– Easily shared, copied, and transmitted.


• Disadvantages?– Less personal?– Deleted easily?– Can get stolen?– The NSA is listening?– Computer viruses?– EM waves and cancer?– Disruption to honeybees?– Kids in the Congo mining Coltan– Polluting when disposed of?


• Disadvantages?– Less personal?– Deletes easily?– Can get stolen?– The NSA is listening?– Computer viruses?– EM waves and cancer?– Disruption to honeybees?– Kids in the Congo mining Coltan– Polluting when disposed of?– Social Networking?– Cyber bullying.


Microwaves: Waves with wavelengths ranging from 1 m down to 1 mm.

existence of infrared.


existence of infrared. Herschel passed sunlight through a prism.


existence of infrared. Herschel passed sunlight through a prism. As the sunlight passed through the prism it divides into a rainbow of colors (spectrum)

– Hershcel used thermometers with blackened bulbs and measured the temperature of the different colors of the spectrum.

• The Herschel Experiment: – Hershcel used thermometers with blackened

bulbs and measured the temperature of the different colors of the spectrum.



Why blackened bulbs?



Why blackened bulbs?Black absorbs all colors so it will conduct more heat to the thermometer / collect data



Why blackened bulbs?Black absorbs all colors so it will conduct more heat to the thermometer / collect data ?

• Results: He observed that the temperature increased from the blue to the red part of the spectrum. – The really cool thing about this experiment…

Then he placed a thermometer just past the red part of the spectrum in a region where there was no visible light and found that the temperature there was even higher.


Then he placed a thermometer just past the red part of the spectrum in a region where there was no visible light.

• The temperature was higher and Herschel concluded that there must be another type of light that we cannot see in this region.

• The temperature was higher and Herschel concluded that there must be another type of light that we cannot see in this region. – This light is now called infrared.

• The temperature was higher and Herschel concluded that there must be another type of light that we cannot see in this region. – This light is now called infrared.

Infrared Radiation: Wavelengths between microwaves and visible light. (heat)


• Infrared radiation is from about a pin head to the cellular level.


• Infrared radiation is from about a pin head to the cellular level. – Infrared can be felt as heat.


• Can be used in meteorology.


• Infrared can be used for military and law enforcement purposes.


• Many animals such as snakes can see in infrared.



Heat loss through the ears to cool down.

• Where is this house losing heat and needs insulation?


• Also used as a heat source.

• Some stains can be seen with UV light, like those seen on crime shows.


Ultraviolet (UV): Has shorter wavelengths than visible light. More powerful than visible light.


Ultraviolet has many wave lengths as well. All of which can cause cancer.UVAUVBUVC


• Avoid UV exposure as it can lead to painful burns and deadly skin cancers.




“Oooooh, I should have

worn sun screen!”

X-Rays: They have smaller wavelengths and therefore higher energy than ultraviolet waves.


• Used for medical examination.


• X-rays can cause cancer if over exposed.• Hands of early x-ray technician.


• Used to study space phenomenon. • X-rays don’t make it through the

atmosphere (good thing) so satellites are used from space.

fission product.

• Gamma rays can cause cancer, and can also be used to treat cancer patients by killing cancer cells.


Laser - Light Amplification by Stimulated Emission of Radiation.Lasers cross over many parts of the EM

scale.


• Laser are light but they are different than regular light because...

– It comes in one color.– It comes in a thin beam– It can be made very intense or not intense at

all and – It can be focused to a tiny spot.


• Activity! Laser are a thin straight beam.– One student gets ready with Aerosol spray

can (Lysol works or others).– Activate laser and student illuminates beam

with reflective particles.

• Laser work by amplifying light (making larger) through radiation.


• Laser work by amplifying light (making larger) through radiation.– One photon stimulates many


• A Photon: A bundle of electromagnetic (or light) energy. Photons are always in motion.

• A Photon: A bundle of electromagnetic (or light) energy. Photons are always in motion. – In a vacuum, light has a constant speed to all

observers of , c = 2.998 x 108 m/s.

• One atom stimulates another atom to release more photons.

• Emission stands for the releasing of photons.

• Radiation means given off.– For lasers it is photons.
