How will you arrange the two mirrors so that whatever?
Two plane mirrors are inclined to each in such a way that A ray incident on first mirror and parallel to second is reflected from first mirror and becomes parallel to the first mirror after second reflection from second mirror.
How will you arrange the two plane mirrors so that whatever may be the angle of incidence the incident ray and the reflected ray from the two mirrors will be parallel to each other?
When two plane mirrors are placed at right angle with each other, then incident ray and reflected ray will always be parallel to each other, whatever may be angle of incidence.
What is the angle between two plane mirrors when there are five images?
Given the angle is θ. So, 360∘60∘= 6, where 6 is an even number. Thus, the images formed will be 5. So, 360∘40∘= 9, where 9 is an odd number.
When a ray of light is incident normally on a plane mirror then the angle of reflection will be?
When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree.
What will be the angle of incidence of a ray of light passing through the center of curvature of a concave mirror?
90 degrees
When light strikes a mirror at an angle of 60 degree what will be the angle of reflection?
= 90 – 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 – 30 degrees) with the mirror surface.
What is the angle of reflection for normal incidence of light ray?
When a ray of light is incident normally on a plane mirror it means that the angle of incidence is 0ₒ. From the law of reflection, we find that angle of reflection is also 0ₒ. Thus, for normal incidence on a plane mirror, angle of incidence and angle of reflection are 0ₒ.
