Light – Reflection and Refraction

Front

What makes things visible in a room?

Back

Light, such as sunlight, helps us to see objects by reflecting off them.

Front

What is the path of light usually indicated as?

Back

A ray of light.

Front

What happens when light encounters a small opaque object?

Back

Light tends to bend around it, an effect known as diffraction.

Front

What does the modern quantum theory of light reconcile?

Back

The particle properties of light with its wave nature.

Front

What are the two laws of reflection of light?

Back

(i) The angle of incidence is equal to the angle of reflection. (ii) The incident ray, the normal to the mirror at the point of incidence, and the reflected ray all lie in the same plane.

Front

What type of image is formed by a plane mirror?

Back

A virtual and erect image that is equal in size to the object.

Front

What is a spherical mirror?

Back

A mirror whose reflecting surface forms a part of the surface of a sphere.

Front

What happens to the image when you view your face in a curved surface like a spoon?

Back

The image may appear smaller or larger depending on the curvature of the surface.

Front

What is the significance of studying the properties of light?

Back

It helps us explore various optical phenomena in nature.

Front

What is the effect of light traveling in straight lines?

Back

It leads to the formation of sharp shadows by opaque objects.
