1.	Q. 25 a diffraction pattern is obtained using a beam of red light. What happens if the red light is replaced by blue light
Answer» ength is INVERSELY proportion to nf=1/n-1 (where n is REFRACTIVE index)we know that blue light has more refractive index then red colourso focal length of convex lens will INCREASE when blue light is used instead of red COLOR
