Question 4 :
Why there are two parallel plane mirrors in a barber shop?
Question 5 :
Plane mirrors are arranged parallel to each other to get :
Question 6 :
The line joining the pole and the centre of curvature of a mirror is called the
Question 7 :
For an object at infinity, a concave mirror produces an image at its focus which is<span><br></span>
Question 9 :
A point object is placed mid-way between two plane mirrors at distance 'a' apart. The plane mirror forms an infinite number of images due to multiple reflections. The distance between the first two images formed behind any mirror is:
Question 10 :
When the angle between two plane mirrors is $60°$, how many images will be formed by the mirrors?
Question 11 :
State whether the following statement is true or false :<br>A diverging mirror is used as a rear-view mirror.
Question 12 :
As the angle between the mirrors decreases the number of images formed also decreases.
Question 13 :
To get 9 multiple images the angle between the plane mirrors should be:
Question 14 :
The reflected ray from a plane mirror is incident on another plane mirror which is placed perpendicular to the first. If the angle of incidence on the first mirror is $30^0$, determine the glancing angle of reflection on the second mirror.
Question 15 :
To get 9 multiple images of an object, the angle between two plane mirrors should be:
