- 254nm is equivalent to 2.54 × 10-⁷metres.
- The frequency of a radiation that has a wavelength of 254nm is 1.18 × 10¹⁵Hz
How to calculate frequency?
Nanometers is an SI subunit of length equal to 10-⁹ metres. It has a symbol of nm.
The conversion factor of metres to nanometers is as follows:
1 nanometres = 1 × 10-⁹ metres
Hence, 254 nanometers is equivalent to 2.54 × 10-⁷metres.
The frequency of a wave can be calculated using the following formula:
wavelength = wave velocity/frequency
frequency = 3 × 10⁸ ÷ 2.54 × 10-⁷
Frequency = 1.18 × 10¹⁵Hz
Therefore;
- 254nm is equivalent to 2.54 × 10-⁷metres.
- The frequency of a radiation that has a wavelength of 254nm is 1.18 × 10¹⁵Hz
