Final answer:
The frequency of ultraviolet light with a wavelength of 274 nm can be calculated using the formula speed of light (m/s) / wavelength (m).
Step-by-step explanation:
The frequency of ultraviolet light with a wavelength of 274 nm can be calculated using the formula:
frequency (Hz) = speed of light (m/s) / wavelength (m)
First, we need to convert the wavelength from nanometers to meters. There are 1,000,000,000 nm in a meter, so 274 nm is equal to 274 × 10-9 m.
Next, we need to use the value for the speed of light, which is approximately 3.00 × 108 m/s.
Using these values, we can calculate the frequency:
frequency = (3.00 × 108 m/s) / (274 × 10-9 m)
= 1.09 × 1015 Hz.
