Understanding Light Refraction Concepts

The video tutorial explains the concepts of reflection and refraction. It begins by discussing how light reflects off surfaces like mirrors, allowing us to see reflections. The tutorial then transitions to refraction, illustrating how light bends when passing through curved glass, affecting its direction. These principles are fundamental in understanding how devices like eyeglasses and microscopes function.

What is the process called when light bounces off a surface like a mirror?

• Reflection

• Absorption

• Diffusion

• Refraction

In the context of light, what happens when it hits tiny particles in water?

• It disappears

• It bounces off

• It gets absorbed

• It refracts

What happens to light when it passes through a curved piece of glass?

• It stops

• It reflects

• It bends

• It scatters

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

• Refraction

• Diffusion

• Dispersion

• Reflection

Which of the following devices uses the principle of refraction?

• Mirror

• Speaker

• Microscope

• Blackboard

How do eyeglasses help people see better?

• By refracting light

• By diffusing light

• By absorbing light

• By reflecting light

What is the origin of the word 'refraction'?

• To reflect

• To scatter

• To bend

• To break up

Which of the following is NOT an example of refraction?

• Magnifier

• Mirror

• Telescope

• Eyeglasses
