Question

Wavelength is 6.25x10^7 m whats the frequency

Answer 1

Answer:

$\huge\boxed{\sf f=4.8 \ Hz}$

Explanation:

Given Data:

Wavelength = λ = 6.25 × 10⁷ m

Speed of light = c = 2.998 × 10⁸ m/s

Required:

Frequency = f = ?

Formula:

$\displaystyle f=\frac{c}{\lambda}$

Solution:

Put the givens in the formula.

$\displaystyle f=\frac{2.998 \times 10^8}{6.25 \times 10^7} \\\\f=0.48 \times 10^1\\\\f=4.8 \ Hz\\\\\rule[225]{225}{2}$
