Answer:
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
