There are two laws of refraction of light. these are : a) Incident say , refracted ray and normal lie on same plane . The concept of plane is shown…
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…
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…
लक्ष्य की उंचाई सफलता को गति और उर्जा प्रदान करती है। परन्तु ऐसा लक्ष्य जो किसी बच्चे की क्षमता से अत्यधिक है । वह बच्चे को मानसिक रोगी या पागल…
Cause of Refraction : The speed of the light in different transparent substances is different. For example speed of light in air is 3×10⁸ m/s and that of in glass…
Refract means bending. The bending of ray of light when it pass from one medium to another medium is known by a term called refraction. Refraction of Light happens due…
