What is meant by incident ray
|
The ray of light which falls on the mirror surface is called incident ray
|
|
What is meant by reflected ray
|
The ray of light which is sent back by the mirror is called reflected ray
|
|
How many reflected rays can there be for a given single incident ray falling on a plane mirror
|
Only one
|
|
What do you understant by point of incidence
|
The point at which the incident ray strikes the mirror is called the point of incidence
|
|
What is normal in the reflection of light from a plane mirror
|
The normal is aline drawn at right angles to the mirror surface at the point of incidence
|
|
Define angle of incidence
|
The angle between incident ray and normal is called the angle of incidence
|
|
Define angle of reflection
|
The angle between the reflected ray and normal is called the angle of reflection
|
|
A ray of light is incident on a plane mirror at an angle of 30 degree.what is the angle of reflection
|
30 degree
|
|
An incident ray make an angle of 75 degree with the surface of plane mirror what will be the angle of reflection
|
75 degree
|
|
A ray of light is incident normally on a plane mirror.where will this ray of light go after reflection from the mirror
|
The ray of light is reflected back along the same path
|
|
What is the angle of reflection when ray of light is incident normally on a plane mirror
|
Angle of reflection is zero
|
|
What is the angle of incident of a ray if the reflected ray is at 90 degree to the incident ray
|
It is 45 degree
|
|
Name the apparatus which is used to obtain a thin beam of light
|
Ray box
|
|
What type of reflection of light takes place from:
a. a rough surface b. a smooth surface |
A. diffuse reflection takes place from rough surface
b. regular reflection takes place from smooth surface |
|
Which type of reflection of light a) ,regular reflection or b) diffuse reflection leads to the formation of images
|
A. it produces clear image of an object
b. no image is formed |
