Get started for freeThere are two categories of ultraviolet light. Ultraviolet A (UVA) has a wavelength ranging from 320 nm to 400 nm. It is necessary for the production of vitamin D. UVB, with a wavelength in vacuum between 280 nm and 320 nm, is more dangerous because it is much more likely to cause skin cancer. (a) Find the frequency ranges of UVA and UVB. (b) What are the ranges of the wave numbers for UVA and UVB?
A circular wire loop has a radius of
In the 25-ft Space Simulator facility at NASA's Jet Propulsion Laboratory, a
bank of overhead arc lamps can produce light of intensity 2500 W/m
A monochromatic light source with power output 60.0 W radiates light of
wavelength 700 nm uniformly in all directions. Calculate
