Mirrors-Lenses

Front

What is a mirror?

Back

A mirror is a reflective surface that reflects light, allowing us to see images of objects.

Front

What is the difference between a convex mirror and a concave mirror?

Back

A convex mirror diverges light rays and produces virtual images, while a concave mirror converges light rays and can produce real images.

Front

What is a lens?

Back

A lens is a transparent optical device that refracts light to form images.

Front

What is a convex lens?

Back

A convex lens is thicker in the middle than at the edges and converges light rays to a focal point.

Front

What is a concave lens?

Back

A concave lens is thinner in the middle than at the edges and diverges light rays.

Front

What is the focal point of a lens?

Back

The focal point is the point where parallel rays of light either converge or appear to diverge after passing through the lens.

Front

What is the principle of reflection?

Back

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

Front

What is diffuse reflection?

Back

Diffuse reflection occurs when light hits a rough surface and scatters in many directions.

Front

What type of image does a concave mirror produce when the object is beyond the focal point?

Back

A concave mirror produces a real, inverted image when the object is beyond the focal point.

Front

What type of image does a convex mirror produce?

Back

A convex mirror always produces a virtual, upright image.
