Q: A lemon kept in water in a glass tumbler appears to be bigger than its actual size when viewed from the outside. This is because of :
  • A. reflection of light
  • B. internal reflection of light
  • C. refraction of light
  • D. diffraction of light
Correct Answer: Option C - When light passes from one medium to another, it deviates from its path. This action is called refraction of light and it is the process of moving towards the normal after the ray of light enters the denser medium and moving away from the normal after entering the rarer medium. Example- (a) When a pencil is placed in a glass filled with water, the pencil looks bent. (b) When a coin is placed in a tub filled with water, the coin appears slightly above the base of the tubs floor. (c) A lemon placed in a glass filled with water appears larger than its actual size when viewed from the out side
