Question

Wavelength is 6.25x10^7 m whats the frequency

Answer 1

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

Step-by-step explanation:

Given Data:

Wavelength = λ = 6.25 × 10⁷ m

Speed of light = c = 2.998 × 10⁸ m/s

Required:

Frequency = f = ?

Formula:

`\displaystyle f=(c)/(\lambda)`

Solution:

Put the givens in the formula.

`\displaystyle f=(2.998 * 10^8)/(6.25 * 10^7) \\\\f=0.48 * 10^1\\\\f=4.8 \ Hz\\\\\rule[225]{225}{2}`
