Which wave, A or B, has higher energy?
Sample Response: Yes, Chayse's results are reasonable because all parts of the electromagnetic spectrum travel at the speed of light. By multiplying his results for frequency and wavelength, I can see that the velocity of the UV ray is close to the speed of light. What did you include in your response? Check all that apply.UV rays travel at the speed of light.Frequency times wavelength equals velocity.The velocity calculated from Chayse’s results is nearly equal to the speed of light.

The speed of all electromagnetic waves is 3.00 × 108 meters per second. What is the wavelength of an X-ray with a frequency of 1.18 × 1018 Hz?
Which change will increase the speed of a sound wave traveling in a solid aluminum rod?
Chayse is working on analyzing the electromagnetic spectrum, focusing on ultraviolet rays. He determines that a UV ray has a frequency of 1.53 × 1016 Hz and a wavelength of 1.96 × 10-8 m. Are his results reasonable? Explain your answer.
Yes, Chayse's results are reasonable. All electromagnetic waves, including ultraviolet rays, travel at the speed of light (approximately 3.00 x 10^8 m/s). When you multiply the frequency (1.53 x 10^16 Hz) by the wavelength (1.96 x 10^-8 m), the product is approximately 2.9988 x 10^8 m/s, which is very close to the speed of light.
