Question

Wavelength of ray of light is 0.00006 m . it is equal to a) 6 micron b) 60 micron c) 600 micron d) 0.6 micron

Answer 1

1 micron = 10⁻⁶ m
so, 60 micron = 10⁻⁵ m
it's (b)

Answer 2

Wavelength of ray of light is b) 60 micron

Given:

Wavelength of ray of light = 0.00006 m

Solution:

The distance between peaks of a wave, particularly the points in a sound wave or electromagnetic wave.

Thereby,

Wavelength is expanded as $6 \times 10^{-5} \ m$

Now to convert this unit of meter into micron, the value must be divided by $10^{-6}$ as

$1 \ micron = 10^{-6} \ m$

Therefore,

$Wavelength =\frac{6 \times 10^{-5}}{10^{-6}} \ micron$

Wavelength of ray of light = 60 micron
