Question

Arrange the following in descending order of wavelength: X-rays, Radio waves, Blue light, Infrared light

Answer 1

The sequence u require is as follows
RADIO WAVES
INFRARED LIGHT
BLUE LIGHT
X RAYS

Answer 2

Answer: Radio wave > infrared light > Blue light > X-rays

Explanation:

According to wave length

X-rays = 1 nm - 10 nm

Radio waves = 1 m - 10 m

Blue light = 440 nm - 485 nm

Infrared light = 700 nm - $10^{5}nm$

So, in the descending order

Radio wave > infrared light > Blue light > X-rays

Hence, this is the required solution.
