4. Effects of Refraction of Light Physics Class 10

There are many effects of the refraction of life in our day to day life. For example I am citing few of them. a) The partly immersed stick appear to be bend at the surface of the water. b) The coin kept in water appears raised upward. c)The water of a pool appear less depth. d)Stars appear to twinkle in the sky when the sky remains clear. e)A lemon immersed in water appears to be bigger in size. All these are discussed in the above video. If you have any confusion then comment below.

3 Three Cases of Refraction of Light Physics Class 10

Case1: When ray of light travels from rarer medium like air to a denser medium like glass then it bends towards normal. Case 2: When ray of light travels from denser medium like glass to a rarer medium like air then it bends away from the normal. Case 3: When ray of light travels from rarer medium like air to a denser medium like glass and again emerges to the previous rarer medium then it suffers a lateral displacement as shown in the figure.

E.G three words are dictated at a time with a provision of time so that learner can write them. After that those words are written so that you may check and correct those. -These words are those type in which mistakes are done by many learner.
