Question

When you go out into the sun, the UV light can give you a tan. UV light has a frequency of 7.89 x 1014 Hz. What is the wavelength of UV light?

Please use 3 x 108 m/s for the speed of light (c).

Answer 1

Answer:

Explanation:

Formula and givens

• λ = c / f
• λ is the wavelength
• c = the speed of light
• f = the frequency
• c = 3*10^8
• f = 7.89 * 10^14

λ = ?

Solution

λ = 3*10^8 / 7.89*10^14

λ = 3*10^8/7.89*10^14

λ = 2.36 * 10^7

λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
