The image below shows a photo taken with a built-in lens of a digital camera. The bottom photo is taken with the same camera, but with an additional wide-angle lens.
Which wave phenomenon best explains the distortion of the bottom image compared to the top?
The picture of the top is basically a clear image of the building and below it is the exact same building but it is blurred
Diffraction
Dispersion
Reflection
Polarization

vapour or gas assuming atmospheriv pressure

i think the answer would be reserve.

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.
