Answer:
Microwaves, visible light, ultraviolet light, x-rays, γ-rays
Explanation:
The energy of any wave is given by :

h = Planck's constant
is the frequency of wave
It is clear that the energy of any wave is directly proportional to its frequency. Gamma rays have maximum frequency. Out of given options microwaves have least frequency.
So, the increasing order of energy is "microwaves, visible light, ultraviolet light, x-rays, γ-rays". Hence, the correct option is (5).
all the allials must be aligned in the same direction
magnets are affected by heat, drops, and improper storage
