What is the wavelength of light with a frequency of 7.66*10^14 hz?

Wavelength = 0.4×10⁻⁶ m

Explanation:

Given data:

Wavelength of light = ?

Frequency of light = 7.66 × 10¹⁴ Hz

Solution:

Formula:

speed of light = wavelength × frequency

Wavelength = speed of light /  frequency

Wavelength = 3×10⁸ m/s / 7.66 × 10¹⁴ Hz

Hz = s⁻¹

Wavelength = 3×10⁸ m/s / 7.66 × 10¹⁴s⁻¹

Wavelength = 0.4×10⁻⁶ m

the answer is d.) potassium

diaria maybe go see a doctor about that
