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.

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.
