Q)
(chatquestion)...(b) The wavelength of visible light ranges from 2, = 770 nm down to 22 = 380 nm. What
colors do the wavelength 2, and 2; corespond to, respectively? Why is that particular
cange.of wavelengths visible?
(c) The double -slit arrangement is illuminated with light from a mercury vapor lamp filte
30 that only the strong green line (=546 nm) is visible. The slits are 0.12 mm apart, an
the screen on which the interference pattern appears is 55 cm away.
