Determine the smallest thickness of the film for which reflected green light of wavelength 540 nm interfere destructively. Express your answer with the appropriate units.

Explanation:

Given

Wavelength of green light

For destructive interference by reflection the path difference is an integral multiple of wavelength so

where

n=refractive index of medium

suppose water is the medium

so

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
