General Science - Physics MCQs


Q.  In which of the following respects, the ultra-violet radiations are similar to white light?
1: Both obey the laws of reflection and refraction
2: Both travel with same speed in vacuum
3: Both are equally active chemically
4 :Both are scattered equally
Select the correct option from the codes given below:


a. Only 1
b. Only 1 & 2
c. Only 1, 2 & 3
d. 1, 2, 3 & 4


ANSWER: See Answer
 
Both obey the laws of reflection.
Both obey the laws of refraction.
Both travel with the speed of 3 × 108 ms–1.
Ultraviolet waves get readily scattered as compared to visible light
Ultraviolet waves are chemically more active than visible light
