Question

give scientific reason for each of the following (1) a stick placed oblique In a beaker containing water appears to be bent​

Answer 1

Explanation:

its just due to refraction of light which occurs because the water is re acting as a mirror

Answer 2

Answer:

Explanation:

The  scientific reason because of which a  a stick placed oblique in a beaker containing water appears to be bent​ is a phenomenon called refraction of light .

Refraction of light

Refraction of light is the phenomenon of bending of light when it passes from a denser to rarer medium or vice-versa.

Laws of refraction

$\bigstar$ The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

$\bigstar$ The incident ray refracted ray, and the normal all lie in the same plane.

Some common examples of refraction that we come across are:-

• Twinkling of stars  in sky.
• Lenses in camera.
• Object looks near to the surface of water.
• Rainbow is formed due to refraction of light .
