Diffraction
Explanation:
The phenomenon through which a beam of light spreads out after leaving the flashlight and the beam grows wider and wider is known as diffraction.
Diffraction is one of the characteristics of waves. It implies the ability of waves to bend round an obstacle. The photons of light are able to bend round obstructions and continue to infinity in space.
The rays grow bigger and bigger due to constructive interference of the waves along the way.

Answer:
It is always the same as it was before the collision.
Answer:
C) 24.4°
Explanation:
let nd = 2.419 be the index of refraction of diamond and na = 1.0 be the index of refraction of air and ∅c be the critical angle.
according to Snell's Law:
sin(∅c) = na/nd
sin(∅c) = (1.0)/(2.419)
∅c = 24.4°
Answer:
Explained
Explanation:
The aperture is the place through which all the light enter into the telescope.
when the aperture is bigger more light coming from outside enter the telescope, hence a bigger and clearer image is seen. That is why scientists say the bigger the better.
Moreover, the resolution of the telescope is inversely proportional to the diameter of the aperture.
