Using Huygen's construction, draw a figure showing the propagation of a plane wave reflecting at the interface of the two media. Show that the angle of incidene is equal to the angle of reflection.

Using Huygen's construction, draw a figure showing the propagation of a plane wave reflecting at the interface of the two media. Show that the angle of incidence is equal to the angle of reflection.

How is a wavefront defined? Using Huygen's construction , draw a figure showing the propagation of a plane wave refracting at a plane surface separating two media. Hence verify Snell's law of refraction.

When a light ray is reflected from a wall, the angle of incidence is not equal to the angle of reflection.

In the given figure,the angle of reflection is

Draw a diagram showing the reflection of a light ray from a plane mirror. Label on it the incident ray, the reflected ray, the normal, the angle of incidence i and the angle of reflection r.

When light wave suffers reflection at the interface from air to glass, the change in phase of the reflected wave is equal to

The angle of incidence on a plane mirror is 30^@ . The angle of reflection will be:

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.

A ray is incident on interface of two media at critical angle as shown in the figure.

In the following figures, draw the normal at the point of incidence and then find out its angle of incidence and angle of reflection
