(b) X-rays

(c) $\gamma$-rays

(d) microwaves

Show Answer

Answer:

Correct Answer: 31. (c)

Solution:

  1. (c) Rays Wavelength

[Range in $m$ ]

$X$-rays $1 \times 10^{-11}$ to $3 \times 10^{-8}$

$\gamma$-rays $6 \times 10^{-14}$ to $1 \times 10^{-11}$

Microwaves $10^{-3}$ to 0.3

Radiowaves 10 to $10^{4}$

Wavelength of U.V. Rays ranges from

$6 \times 10^{-8}$ to $4 \times 10^{-7}$.
