Every year , on February 28 , we observe National Science Day . I am writing about my observation and the scientific reason behind that .
Yesterday my mother was preparing lemon pickle. In the beginning , she has put the lemons in a glass container to wash. I had seen the lemons when they were brought from the shop. But when they are immersed in water , all of a sudden , they looked larger in size.
WHY ?
Science has answer to every single doubt. It is the result of a phenomenon called refraction.
When we keep the lemon inside water , the light rays have to travel from a dense medium ( in this case , water ) to the observer . ( in this case , air which is lighter than water in density ).
The law of refraction says that , when light travels from one medium to another , light changes its direction . The denser the medium , thicker the object will appear to the observer.
For example , if we put lemon inside glycerine ; glycerine is having more density than water , the lemon will look more thicker than it was seen when in water .
