The rays of light which are parallel in nature will form
When a ray of light travelling in glass enters into water obliquely:
When a ray of light is incident normally on a surface, then
A ray of light, travelling parallel to diameter of a sphere enters the sphere through a hole at point A as shown in the figure. The inner surface of the sphere is made perfectly reflecting. Find the number of reflections suffered by the ray before coming out of the sphere.
A ray of light travelling in air goes into water. The angle of refraction will be:
