A certain electromagnetic wave has a wavelength of 6.25 x 10-7m. What is the
olasank [31]

Answer: 4.80 * 10¹⁴s⁻¹

Explanation:

Speed = Frequency * Wavelength

So:

Frequency = Speed/ Wavelength

Speed of light = 3 * 10⁸ m/s

Frequency = (3 * 10⁸ m/s) / (6.25 x 10⁻⁷m)

= 4.80* 10¹⁴hz

= 4.80 * 10¹⁴s⁻¹
