Question

Need 2 example of rectilinear propagation in daily life

Answer 1

U man rectilinear propagation of light? ????????????????????????????????!!!!!!!

Answer 2

1. A relatively pure example of refraction can be observed if one places a straight object like a pencil partly in a glass of water and then observes the apparent change in the direction of the image of the straight object when it crosses the surface of the water. 2. A prism is an example of refraction. It also illustrates that the extent of refraction of light depends on the color. In a prism, light is refracted as it enters and as it leaves the prism and the light waves of different colors change directions by different amounts so that when they exit the colors are seen at different angles.
