Find the separation of two points on the moon’s surface that can just be resolved by the 200 in. (= 5.1 m) telescope at mount palomar, assuming that this separation is determined by diffraction effects. the distance from earth to the moon is
3.8×105km
. assume a wavelength of 550 nm for the light.

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
