Select True or False for the following statements about electromagnetic waves. Visible light is often emitted when valence electrons change their state. Gamma rays can be produced in transitions of an atomic nucleus from one state to another. Blue light has a longer wavelength than red. X-rays are produced by a glowing light bulb. The sun's radiation is most intense in the infrared region. Ultraviolet radiation causes common sunburn. A vertical automobile antenna is sensitive to electric fields polarized horizontally.

The primary difference between infrared and visible light is that infrared travels faster than visible light. they have different amplitudes. infrared does not have a magnetic field associated with its electric field. they have different wavelengths. no materials currently known have the ability to reflect infrared.

(1) Radio waves and light are electromagnetic waves and transverse waves that can operate in a medium or in space. What is an Aether or ether? Upon which medium does sound travel the fastest? (2) Some scientists think that ether does exist but does exist in another dimension that we cannot see. Can you elaborate on this?

Light, heat ... energy - are all electromagnetic waves. Discuss the differences between them.

a) What are the different types of “light” (electromagnetic waves), starting from radio waves? Why do you think we can only see such a small portion of the electromagnetic spectrum? Why don’t we see X-rays or microwaves? b) Explain what a photon is and what property of photons relates to different colors of light. c) What is the frequency of light that has a wavelength of 400 nm? What is the color of such light? What is the energy of...

Describe electromagnetic waves, frequency of light, wavelength of light, and speed of light in vacuum and in medium. In your own words, explain index of refraction and light propagation from one medium to another. In your own words, explain polarization and light intensity.

1- What is the difference between energy and intensity as far as light waves are concerned?...

1- What is the difference between energy and intensity as far as light waves are concerned? How would you change the energy? How would you change the intensity? Are these changes independent of one another? Why or why not? a- Discuss what changes you might expect to see if the energy of the light wave was changed for the double slit experiment. Why? b- Discuss what changes you might expect to see if the intensity of the light wave was...
