25.4 and 25.5 Frequency, wavelength, and the
BIO Ultraviolet A and B 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 range 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?
