Understanding Refraction

The video explores the phenomenon of refraction using a pencil in a glass of water. It explains how light bends when it moves from one medium to another, causing the pencil to appear bent or broken. The video discusses the reflection of light from the pencil above the water and how light refracts at the interface between water, glass, and air, altering the perceived position of the pencil.

What phenomenon is being demonstrated with the pencil in the glass of water?

• Dispersion

• Refraction

• Reflection

• Diffraction

What happens to light when it reflects off the pencil above the water?

• It bends towards the water

• It travels straight to the eye

• It scatters in all directions

• It gets absorbed by the pencil

Which part of the pencil does not appear distorted when viewed through the glass?

• The entire pencil

• The part above the water

• The part below the water

• The tip of the pencil

How does light behave when it transitions from water to air?

• It gets absorbed by the air

• It speeds up and bends

• It slows down and bends

• It continues in a straight line

What is the effect of light bending at the interface of different media?

• The object disappears

• The object appears bent or broken

• The object appears smaller

• The object appears larger

What happens to light at the interface between water and air?

• It gets absorbed

• It bends

• It reflects back

• It remains unchanged

Why does the pencil appear broken when viewed through the water?

• Light is refracted as it exits the water

• Light is absorbed by the water

• The pencil is actually broken

• The pencil is distorted by the glass

What is the term used to describe the bending of light as it passes through different media?

• Absorption

• Reflection

• Refraction

• Diffraction

What is the primary cause of the pencil appearing bent in the water?

• Refraction of light

• Absorption of light

• Diffraction of light

• Reflection of light

What is the role of the glass in the refraction of light?

• It reflects the light

• It absorbs the light

• It acts as a medium for refraction

• It distorts the light
