Question

the wavelength of light of frequency 100Hz is

Answer 1

30 $\times$ $10^5$  m/s is the wavelength of light of frequency 100 Hz.

Explanation:

We have to calculate the wavelength of the frequency that we are given.

We know that the speed with which light would travel is 3 $\times$ $10^8$ m/s.

Now how to calculate the wavelength you need to know the relation between wavelength frequency and speed and the relation would be the product of wavelength and frequency would give speed.

Hence to find wavelength applying this formula and solving we get

                             W = $\frac{3 \times 10^8}{100}$ Hz

                           ⇒ W = 30 $\times$ $10^5$

Answer 2

Given - Wavelength of light

Find - Frequency of light

Solution - Wavelength and frequency of light are connected to each other by the formula - c = f * lambda. In this formula, c represents speed of light, f represents frequency and lambda is the wavelength of light.

Now keeping the values in formula to find the wavelength of light. Taking value of speed of light as 3*10⁸ metre/second.

Lambda = 3*10⁸/100

Lambda = 3*10⁶ metres

Thus, the wavelength of light will be 3*10⁶ metres.
