  1. Refraction of Light


  2. Hello! I am Kritika Kapoor I am here because teaching is my passion 2


  3. Content Introduction Refraction Examples 3


  4. Introduction Refraction e Light doesn't travel in straight path or same path in every medium. Refraction means bending of light when it enters obliquely from one transparent medium to another.


  5. Reason of Refraction Change in the speed of light . We know that refraction occurs when light passes across the . The transmission of light across a boundary between two media is boundary between two media. accompanied by a change in both the speed and wavelength of the wave The light wave not only changes the direction at the boundary but also change the speed (either speeds up or slow down) and thus transform into a longer or shorter wavelength. 5


  6. Examples .Bottom of the swimming pool appears higher. Lemon placed in a glass tumbler (water) appears big. A spoon ie. partially immersed in water appears to be bent at the interface of water and air. Lemon appearing larger than its size Lemon Letters of a book appear to be raised when seen through a glass slab. 6


  7. Refraction AIR B GLASS Refraction is the bending of a wave when it enters a medium where its speed is different o The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.. . AIR
