The condition to be met for the critical angle is the angle between the incident

Question

The condition to be met for the critical angle is the angle between the incident ray and the normal is 90°. the angle between the reflected ray and the normal is 90° the angle between the incident ray and the reflected ray is 90°. all of the above. none of the above The condition to be met for the critical angle is the angle between the incident ray and the normal is 90°. the angle between the reflected ray and the normal is 90° the angle between the incident ray and the reflected ray is 90°. all of the above. none of the above the angle between the incident ray and the normal is 90°. the angle between the reflected ray and the normal is 90° the angle between the incident ray and the reflected ray is 90°. all of the above. none of the above the angle between the incident ray and the normal is 90°. the angle between the reflected ray and the normal is 90° the angle between the incident ray and the reflected ray is 90°. all of the above. none of the above the angle between the incident ray and the normal is 90°. the angle between the reflected ray and the normal is 90° the angle between the incident ray and the reflected ray is 90°. all of the above. none of the above

Explanation / Answer

the defination is for critical angleis

" the reflected ray is grazes the principal axis is called critical angle "

so the the angle between the reflected ray and the normal should be 90°

so

the angle between the reflected ray and the normal is 90° is correct
