Consider the following statements about electromagnetic waves and choose the correct ones
S1 : Electromagnetic waves having wavelengths 1000 times smaller than light waves are called

X

-rays
S2 : Ultraviolet waves are used in the treatment of swollen joints
S3 : Alpha and gamma rays are not electromagnetic waves
S4 : de Broglie waves are not electromagnetic in nature
S5 : Electromagnetic waves exhibit polarization while sound waves do not

View answer and explanation

Correct option: A

S1, S4 and S5

Option A (S1, S4 and S5) is correct because X-rays have shorter wavelengths than light, de Broglie waves are matter waves, and electromagnetic waves can be polarized while sound waves cannot.
