Since the angle of incidence is 45° using the law of reflection we can conclude the reflective ray will also make an angle equal to the angle of incidence i.e. 45° with the normal.

<h3>What are the three laws of reflection?</h3>

1)The angle between the incident ray and the normal is equal to the angle between the reflected ray and the normal.

2)The incident ray, the normal and the reflected ray are all in the same plane.

3) Incident ray and refracted ray are on different sides of the normal.

Given:

Light rays strike at an angle of 45° to the plane.

Using the law of reflection we can easily draw the reflective wave.

Important terms:

Angle of incidence - it is the angle at which the light way strikes the plane mirror.

Angle of reflection- it is the angle at which the light way is reflected back by the plane mirror.

Now since the angle of incidence is 45° using the law of reflection we can conclude the reflective ray will also make 45° with the normal.

Hence the angle of incidence is 45° and also the angle of reflection is equal to the angle of incidence i.e.45°.

How is the rotation of the sun, different from the rotation of the earth
vesna_86 [32]

Answer:

The Sun has a north and south pole, just as the Earth does, and rotates on its axis. However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. This is known as differential rotation.

In order to do work, the force vector must be
gregori [183]

As we know that total work done by a force is given by

W = F.d

W = Fdcos\theta

so it is product of force and displacement along same direction

as we can write it as

W = (Fcos\theta)(d)

so it must be the product of force and displacement in same directions so correct answer must be

<u>B. in the same direction as the displacement vector and the motion.</u>
