A large fraction of the ultraviolet (UV) radiation coming from the sun is absorbed by the atmosphere. The main UV absorber in our atmosphere is ozone, O3. In particular, ozone absorbs radiation with frequencies around 9.38×1014 Hz . What is the wavelength λ lambda of the radiation absorbed by ozone?

or 0.32 μm.

Explanation:

Given:

The radiations are UV radiation.

The frequency of the radiations absorbed (f) =

The wavelength of the radiations absorbed (λ) = ?

We know that, the speed of ultraviolet radiations is same as speed of light.

So, speed of UV radiation (v) =

Now, we also know that, the speed of the electromagnetic radiation is related to its frequency and wavelength and is given as:

Now, expressing the above equation in terms of wavelength 'λ', we have:

Now, plug in the given values and solve for 'λ'. This gives,

Therefore, the wavelength of the radiations absorbed by the ozone is nearly or 0.32 μm.

(75°f − 32) × 5/9 = 23.889°c
