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 aboveExplanation / 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
