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

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
