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.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
