Question

when the light is travel from the denser medium to rate medium on which Direction to the light will move ? explain with diagram.

2) when the light is travel from the rarer medium in which direction to the light will move? explain with the neat diagram.

3) when the light travels from the water to air in which direction the light will move explain with neat diagram.​

Answer 1

1. When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law. As you saw before, the larger angle must be in the medium having the lower index of refraction. On the previous pages, that was medium 1, but here it is medium 2.
