What is the meaning of angle of incidence and angle of reflection?
At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
What is called angle of reflection?
Solution : Incident ray – the ray of light falling on the surface AB is called the incident ray. Angle of reflection – the angle formed between the normal and the reflected ray is called angle of reflection. Normal – it is the line drawn perpendicular to the reflecting surface at the point of incidence.
What relationship exists between the angle of incidence and the angle of reflection give reasons?
The angle of incidence is the angle between this normal and the incident ray; the angle of reflection is the angle between this normal and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection.
What is the total angle turned by the ray?
The total angle turned by the ray of light is 80 degrees i.e. the angle between incident ray and the reflected ray is 80 degrees. It is based on simple geometry.
What is inclined mirror?
Inclined mirrors. If the image of an object is viewed in two plane mirrors that are inclined to each other more than one image is formed. The number of images depends on the angle between the two mirrors.
When two plane mirror are placed perpendicularly then images are formed?
Answer : Three images are formed if the plane mirrors perpendicular to each other….
How are two mirror images formed?
If the image of the object is viewed in two plane mirrors that are inclined to each other, more than one image is formed. The number of images formed by two plane mirrors depends on the angle between the mirror. Complete step by step solution: So, 360∘90∘= 4, where 4 is an even number.
