Which is the best example of refraction?

a) an image appears that is exactly like the real object.

b) when put into a container, two mediums do not mix together.

c) a laser beam looks bent when it passes through glass blocks.

d) a concave lens causes an object to appear larger than its actual size.

c would be your answer just did this on usatest prer

Explanation:

Option (c) is correct.

Explanation:

When a ray of light passes from one optical medium to another optical medium, the path of ray of light is deviated, this phenomena is called refraction.

It occurs due to the change in speed of light, as it passes from medium to another.

So, when a laser beam passes through a glass block, the refraction takes place.
