Question

3) An AM radio station has a carrier frequency of 600 kHz. What is the wavelength of the broadcast? UV Rays (Ultraviolet) are part of the electromagnetic spectrum of light produced by the sun. UV-A rays are important for the skin's production of vitamin D; however, they tan and damage the skin. UV-B rays can cause skin cancer. The wavelength of UV-A rays is 320 nm to 400 nm and that of UV-B rays is 280 to 320 nm. What is the range of frequencies corresponding to the two types of rays? Also briefly explain why the UV-B rays are more dangerous than UV-A rays 4)

Explanation / Answer

here,

3)

frequency , f = 600 Hz

the wavelength of broadcast , lamda = c/f

lamda = 3 * 10^8 /(600) m

lamda = 5 * 10^5 m

the wavelength of broadcast is 5 * 10^5 m
