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?

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...

please answe these 2 topic Topic 1: Electromagnetic Waves Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. According to your Knowledge, answer the following questions: - Describe the characteristic of Electromagnetic Waves? - Radio Waves travel along different paths: a. State their names? b. Which of them does Loran-C receiver receive?...
