3. What color in the visible spectrum carries the lowest energy?
4. Radio wave, X-ray waves, and microwave are observed to be travelling in a vacuum. If the waves have a wavelength of 2 x 103 m 2 x 10-9 m, 2 x 10-1 m respectively, which of the three travels the fastest?
5. What will happen to the frequency and wavelength if the energy of the waves decreases?
6. A certain FM radio station broadcasts at 90.5 MHz or 9.05 x 107 Hz. The radio wave travels at the speed of light, what is its wavelength?
7. What electromagnetic wave has the highest energy?
8. Which shows the correct arrangement of the electromagnetic wave in increasing frequency?
9. A radio wave with a frequency of 6.2 x 109Hz is detected to be travelling in space. The value of Planck’s constant is 6.626 x 10-34 Js.
What is the wavelength of the wave?
10. How much energy does the wave carry?
