The frequency of the wave is 4.3 × 10⁹Hz
HOW TO CALCULATE FREQUENCY OF A WAVE:
- The frequency of a wave can be calculated by dividing the speed of the wave (v) by its wavelength (λ). That is;
f = v/λ
Where;
f = frequency (Hz)
v = speed of the wave (m/s)
λ = wavelength (m)
- The speed of a wave is given as 2.5 x 10³ m/s and its wavelength as 5.80 x 10-⁷m, hence, the frequency can be calculated as follows:
f = v/λ
f = 2.5 × 10³ ÷ 5.80 x 10-⁷
f = 2.5/5.80 × 10³+⁷
f = 0.43 × 10¹⁰
f = 4.3 × 10⁹Hz or s-¹
- Therefore, the frequency of the wave is 4.3 × 10⁹Hz.
