Question

if an incident ray makes an angle of 40 degree with the normal, what will be the angle between the reflected ray and the normal ​

Answer 1

Given:

An incident ray makes an angle of 40 degree with the normal.

To find:

Angle between reflected ray and normal ?

Calculation:

• Angle of incidence first two the angle between the incident ray and the normal.

• As per the question, the angle of incidence will be 40°.

As per the LAWS OF REFLECTION:

Angle of incidence = Angle of reflection

• So, angle of reflection will also be 40°.

• Similarly as per the definition of angle of reflection, the angle between the reflected ray and the normal will still be 40°.

$\star$ So, answer is 40°

Answer 2

Answer:

the answer 40 degree

Explanation:

because of the laws of reflection it's written that

angle of incidence is equals to angle of reflection
