Which has a faster speed, the laser from a CD or the light from the fireworks?
3. An FM radio station broadcasts at a frequency of 106.5 MHz (1 MHz = 106 Hz) a. Convert 106.5 MHz into Hz.
b. Calculate the wavelength of the signal.
4. The argon-fluoride laser used in eye surgery emits light at 1.55 x 1015 MHz
a. What is the energy of the laser’s light?
b. What is the wavelength (in nanometers) of the light?
5. What would be the wavelength (in meters) of light necessary to cause electrons to leave the surface of a substance with an energy of 1.20 x 10-19 J?
6. Circle a calculation, or two, above (#1-5) you would like me to make an instructional video for.
