Question

A television station emits waves with a frequency of 2.5 x 10^8 Hz. Electromagnetic waves
travel at a speed of 3.0 x 10^8 m/s.

Calculate the wavelength of the waves emitted by this television station. State the equation
you use.

$\frac{3.0 \times {10}^{8} }{2.5 \times {10}^{8} }$

$\huge\mathfrak\color{Yellow}Given:$

⟹ velocity = 3 × 10⁸ m/s

$\huge\mathcal\pink{Find:}$

★ wavelength (λ) ★

$\huge\mathrm\orange{★\:Formula\:★}$

⟹ velocity of sound = ν λ

so,

⇒ λ = $\frac{velocity (v) }{nu(ν)}$

⇒ λ = $\frac{3 \: × 10⁸m/s }{2.5 × 10⁸ hz}$

⇒ λ = $\frac{3 \: m/s }{2.5hz}$

⇒ λ = 1.2 m

wavelength = 1.2 m
