Question

the frequency range of visible light is from 3.75*10 to the power 14hz to 7.5 *10 to the power 14 hz calculate its wavelength . take speed of light is 3*10 to the power meter per second

Answer 1

c = vλ or we can write this as: λ = c/v

First of all we will consider the first case:

λ₁ = c/v₁

c = 3 x 10⁸ m/s

v₁ = 3.75 x 10¹⁴ Hz

λ₁ = 3 x 10⁸ / 3.75 x 10¹⁴

= 0.8 x 10⁻⁶ m

Now we will consider the second case

λ₂ = c/v₂

c = 3 x 10⁸ m/s

v₂ = 7.5 x 10¹⁴ Hz

λ₂ = 3 x  10⁸ / 7.5 x 10¹⁴

= 0.4 x 10⁻⁶ m

So the wavelength range will be

0.4 x 10⁻⁶ m - 0.8 x 10⁻⁶ m
