A normally incident ray reflected at an angle of `90^(@)` . The value of critical angle is

What is the angle of incidence of a ray if the reflected ray is at an angle of 90^(@) to the incident ray?

A ray of light is reflected at an angle of 15^@ . If the angle of incidence is doubled, then the angle of reflection will be

What is the angle of incidence of a ray if the reflected ray is at an angle of 90^@ to the incident ray ?

What is the angle of incidence of a ray if the reflected ray is at an angle of 90^@ to the incident ray?

What is the angle of incidence of a ray if the reflected ray is at an angle of 90^@ to the incident ray ?

The diagram below shows a light ray striking and reflecting from a plane mirror AO is the incident ray and OB the reflected ray. The angle between the incident ray and the reflected ray is 120^@ . What is the value of the angle of reflection?

Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.
