Question

1. The basic cause of refraction is the change in the speed
of light as it goes from one medium to another._____

2. In an optically denser medium, the speed of light is
more than the speed of light in vacuum._____
Please give correct answer its true or false​

Answer 1

Answer:

Refraction of light is caused due to the change in the speed of light in different mediums. Refraction is the bending of the path of a light wave as it passes from one material into another material. The refraction occurs at the boundary and is caused by a change in speed of the light wave upon crossing the boundary.
