Question

An electromagnetic wave has a frequency of 2.90 × 1014 Hz. What is the wavelength of the wave? Question 17 options: 1.03 × 10–6 m 9.60 × 10–7 m 8.70 × 1022 m 2.61 × 10–21 m

Answer 1

Answer:

Wavelength of the wave is $1.034 \times 10^{-6} m$

Explanation:

Wavelength of the wave is given by

$\lambda=\frac{v}{f}$

Here,

$f=2.90\times 10^{14} Hz\\v=3\times 10^8 m/s$

wavelength is

$\lambda=\frac{v}{f} \\\lambda=\frac{3 \times 10^8}{2.90\times 10^{14}}\\\lambda=1.034 \times 10^{-6} m$

Option A is correct
