If a Ray of light is incident on a plane mirror such that it makes an angle of 30 degree with the mirror then what will be the angle of reflection?

Question

Answer

Angle of reflection will be 60...... because ...30 is the angle made by the incident Ray ...i.e. 30 + i =90.... therefore i=9p-30=60.....so angle of reflection is 60.....

Answer

30 degrees....in a plane mirror angle of incidence is equal to the angle of reflection

Answer

Plane mirror always form real image

Answer

Angle of Incidence and Reflection

When a ray of light strikes a surface, it undergoes reflection. The angle at which the incident ray strikes the surface is called the angle of incidence, and the angle at which the reflected ray bounces off the surface is called the angle of reflection. According to the law of reflection, the angle of incidence is equal to the angle of reflection.

Incident Ray and Plane Mirror

In this scenario, a ray of light is incident on a plane mirror at an angle of 30 degrees. Let's analyze the situation step by step.

1. Incident Ray: The incident ray is the ray of light that approaches the mirror. In this case, it is making an angle of 30 degrees with the mirror.

2. Normal: The normal is a line drawn perpendicular to the surface of the mirror at the point of incidence. It helps in measuring the angle of incidence and reflection.

3. Angle of Incidence: The angle of incidence is the angle between the incident ray and the normal. In this case, the angle of incidence is 30 degrees.

4. Angle of Reflection: The angle of reflection is the angle between the reflected ray and the normal. According to the law of reflection, the angle of reflection is equal to the angle of incidence. Therefore, the angle of reflection in this case would also be 30 degrees.

Explanation:

When the incident ray strikes the plane mirror, it gets reflected back according to the law of reflection. The angle of incidence and reflection are always equal for a plane mirror. This means that if the incident ray makes an angle of 30 degrees with the mirror, the reflected ray will also make an angle of 30 degrees with the mirror.

The law of reflection holds true for any angle of incidence, as long as the surface is flat and the mirror is plane. The reflected ray will always be on the opposite side of the normal, forming an angle equal to the angle of incidence.

Thus, in this scenario, the angle of reflection will be 30 degrees, as it is equal to the angle of incidence.
