1. A) radio wave has a wavelength of 21 cm. What is the wavelength in meters? (Give your answer in meters rounded to exactly 2 decimal places). B)Use your previous answer and the speed of light (c = 3 · 108 m/s) to calculate the frequency of a 21 cm radio wave. Give your answer in Hz, no decimal places. C)Use your previous answer to calculate the frequency of a 21 cm radio wave. This time, give your answer in GHz, rounded to exactly one decimal place. (Note that 1 GHz = 109 Hz).
Please anwer the quesiton correctly and take your time, i read the guideline and honor code and im allowed to have Submit only one question at a time under the appropriate subject.
