What is the wavelength of radiation that has a frequency of 6.912 * 10^15 s-1?

Wavelength = 4.34x10⁻⁸m

Explanation:

In a wave, frequency is inversely proportional to wavelength where the constant is the speed of light. The equation is:

Wavelength = Speed of light / Frequency

The speed of light is 3.0x10⁸m/s

Replacing:

Wavelength = 3.0x10⁸m/s / 6.912x10¹⁵s⁻¹

Wavelength = 4.34x10⁻⁸m
