Card 1Reflection of Light

What is reflection of light?

Answer

Reflection is the bouncing back of light after it falls on a surface. A smooth and shiny surface reflects light well.

Card 2Laws of Reflection

State the two laws of reflection.

Answer

1. The incident ray, reflected ray, and the normal all lie in the same plane. 2. The angle of incidence is equal to the angle of reflection: ∠i = ∠r.

Card 3Reflection of Light

What changes during reflection of light?

Answer

During reflection, speed, frequency, and wavelength of light do not change.

Card 4Plane Mirror

A plane mirror shows a person's full image. How much mirror height is needed?

Answer

A plane mirror of half the person's height is enough to see the full image.

Card 5Plane Mirror

Why does a plane mirror show left-right reversal?

Answer

The mirror reverses front-back direction, not left-right directly. This causes lateral inversion, so left becomes right and right becomes left in the image.

Card 6Plane Mirror Motion

A person moves towards a plane mirror with velocity v. What happens to the image?

Answer

The image also moves with velocity v towards the mirror. The velocity of the image with respect to the object is 2v.

Card 7Images

What is a real image and what is a virtual image?

Answer

A real image is formed by actual intersection of rays and can be projected on a screen. A virtual image is formed by apparent meeting of rays and cannot be projected on a screen.

Card 8Types of Reflection

How do regular reflection and diffused reflection differ?

Answer

Regular reflection takes place from smooth surfaces and keeps reflected rays orderly. Diffused reflection takes place from rough surfaces and spreads rays in many directions, though the laws of reflec…
