stions:
1. What is the bending of light as it travels from one type of
material to another, like from air to water?
2. Why do you think the pencil as bent?​


Sagot :

Answer:

1. Refraction

2. It looks bent because of Refraction, When a light ray passes from air into water a similar thing occurs: the light ray is bent as it strikes the surface of the water. This 'bending of a ray of light' when it passes from one substance into another substance is called refraction.

More info on refraction:

  • In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
