FERMAT'S PRINCIPLE OF LEAST TIME "From all the possible paths to go from one point to another, light takes the path which requires least time." 5 rath-2 Light will choose to go through path 2
Using this concept we can have an idea about reflection and refraction. 2 7-1 P-2 (Path-2) Most appropriate path for least time considerations
General Optics Questions Q. What will be the colour of bulb with respect to observer's eye? wati gen Ans. It seems Green. Colour is the property of Frequency and frequency depends on source. It will not change with changing medium
Frequency remains same on changing medium. Wavelength will change on changing medium Speed of light will change with changing medium
* We can see things around us due to Two major reason :- 1-> One is due to Emission (or Radiation) of light. 2Due to reflection of light.
Q. Which ballon will burst first? Blue Red Red LASER. Red SER * Blue colour reflects blue light and absorbs rest of the colours. Similarly Red reflects red and absorbs rest.
