Answer 1

Answer:

refraction is the correct answer

Answer 2

This happens due to the, peculiarity of (b)refraction of light.

how it functions?

• The beam of light from the coin goes from a denser medium to a more rarer medium .
• In this cycle it twists from the ordinary . The point from which the refracted beams seem to come gives the clear place of then.
• At the point when enters from water to glass to air then it gets refracted a few times because of which the Reflected light enters to our from a distance somewhat over the coin.
• In this way, the coin seems, by all accounts, to be marginally upraised.
