Question

What is the wavelength of a wave having a frequency of 6.2×10 to the 14th inverse seconds

Answer 1

4.835 × 10^-7 m

Step-by-step explanation:

We are given;

• The frequency of the wave as 6.2×10^14 Hz

We are supposed to calculate the wavelength;

• Assuming the wave has a speed equivalent to the speed of light, 2.998 × 10^8 m/s, then we can calculate the wavelength.

• We know that;

Velocity, c = frequency, f × wavelength, λ

• Therefore, rearranging the formula;

λ = c ÷ f

In this case;

Wavelength, λ = 2.998 × 10^8 m/s ÷ 6.2×10^14 Hz

= 4.835 × 10^-7 m

Therefore; wavelength of the wave is 4.835 × 10^-7 m
