Reflection from Plane Mirror

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

Define the angle of incidence.

Back

The angle of incidence is the angle between the incident ray and the normal line at the point of incidence.

Front

Define the angle of reflection.

Back

The angle of reflection is the angle between the reflected ray and the normal line at the point of reflection.

Front

What is a normal line in the context of reflection?

Back

A normal line is an imaginary line drawn perpendicular (90 degrees) to the surface of the mirror at the point of incidence.

Front

What type of image is formed by a plane mirror?

Back

A plane mirror forms a virtual image that is upright and the same size as the object.

Front

What is a real image?

Back

A real image is formed when light rays converge and can be projected onto a screen; it is inverted.

Front

What is a virtual image?

Back

A virtual image is formed when light rays appear to diverge from a point; it cannot be projected onto a screen.

Front

How does the distance of the object from the mirror affect the image?

Back

The distance of the object from the mirror is equal to the distance of the image from the mirror.

Front

What happens to the image when the object is moved closer to the mirror?

Back

The image moves closer to the mirror and remains the same size and orientation.

Front

What is the significance of the angle of reflection in practical applications?

Back

The angle of reflection is crucial in designing optical devices like periscopes and telescopes.
