alleryIn vacuum, infrared λ=1 μm and UV λ=0.25 μm. Which frequency is greater?
AUV, by a factor of 2
BUV, by a factor of 4
CInfrared, by a factor of 2
DInfrared, by a factor of 4
Answer & Solution
Correct answer: B. UV, by a factor of 4
Frequency varies inversely with wavelength, so the quarter-wavelength ultraviolet beam has four times the infrared frequency.
