Ablock of gold is illuminated with uv light at a wavelength of 1.6x10-11 meters. what is the frequency of this light ?

f = 1.87 × 10¹⁹ s⁻¹

Explanation:

Given data:

Wavelength of light = 1.6 ×10⁻¹¹ m

Frequency of light = ?

Solution:

Formula:

speed of light = wavelength × frequency

Frequency = speed of light / wavelength

speed of light = 3× 10⁸ m/s

Now we will put the values in formula:

Frequency = speed of light / wavelength

f =  3× 10⁸ m/s / 1.6 ×10⁻¹¹ m

f = 1.87 × 10¹⁹ s⁻¹

the answer is the first option

explanation:

just googled it m8. not that hard

lol

that tool would be a compass
