Question

Q1)what will be the image distance if the object is 5m in front of a plane mirror?


Q2)which shpericle mirror is called a converging mirror?Draw a lablled diagram to show how light converges after reflection from a converging mirror.

Q3) What is the normal temparature of human body ? what is the range of a clinical thermometer?​

Answer 1

1. Image distance will be equal to object distance in a plane mirror.

• So, u = v = 5 metre.

2. Concave mirrors are known as converging mirror because the light rays after reflection converge towards each other.

• On the other hand, convex mirrors are called DIVERGING mirror because they diverge the light rays away from one another.

3. Normal temperature of human body is 37°C.

• Range of clinical thermometer is 35°C to 42°C.
