Question

Match the column A with those column B

Column 1	Column 2
Reflection due to which the image is not sharp	Real Image
Image which can be seen on a screen	Dispersion
Rainbow	Irregular reflection
Concave mirror	Convex mirror
Rear view mirror	Dentist's mirror

Answer 1

A. Reflection due to which the image is not sharp - iii. Irregular reflection

1. In irregular reflection, the rays are reflected in many different directions. This is why an irregular reflection image is not sharp.

B. Image which can be seen on a screen- i. Real image

1. A real image can be obtained on the screen as the light rays coming from the object meet each other either after reflection or after refraction.

C. Rainbow - ii. Dispersion

1. Rainbow is produced after the rain, by reflection, refraction, and light dispersion process in droplets of water.
2. All such events develop a light spectrum in the sky is called a rainbow.

D. Concave mirror- v. Dentist mirror

1. f the object is placed between the focus and pole of a concave mirror, it provides a virtual enlarged and erect image.
2. So, the dentists use it as a magnifying tool.

E. Rearview mirror- iv. Convex mirror

1. Convex mirrors have a very wide field of view as they are curved outwards.
2. So, the convex mirrors enable the driver to view a much larger area than a plane mirror.

Hence, the correct answer is A. -iii., B. -i., C.-ii., D.-v., E.- iv.
