Question

i) A coin is kept in water in a glass tumbler appears to be bigger than its
actual size when viewed from the sides. In this case water and glass acts as
which type of lens?

Answer 1

Answer:

convex lens

Explanation:

Due to this different light rays meet above the actual position of the lemon. This refraction causes the bending of rays. The glass tumbler with water behave like convex lens and thus, the lemon appear to be bigger than its actual size when placed in glass tumbler filled with water

Answer 2

Answer :

1) Light is refracted as it passes from water into the Air .

2) Glass tumbler with water acts as Convex lens, which curves outward in the middle and can focus light rays on magnifying the object.

Explanation :

1) Reflection is the phenomenon of rebound of light when it strikes medium on a plane where as Refraction is the process of bending of light when it

Passes through the medium.

2) The light entering the medium Returns into the same direction in reflection, whereas in refraction light entering the medum travels from one medium to another.

3) In reflection , Angle of incidence = angle of reflection. In Refraction angle of incidence is not equal to angle of refraction.

4) a coin kept in water ina glass tumbler appear to be bigger than its actual size, when viewed from the slides due to refraction at the glass surface in going from denser to rarer medium
