The photometric radiation equivalent Kcd is defined for monochromatic radiation with a frequency of 540 THz. What wavelength and what color is this light? 1. Enter the calculation and 2. explain how you determined the color of the light. 3. What is the wavelength range visible to the human eye?3.1 Which colors correspond to the wavelengths at the edge of the range?

Answer 1

1. $\lambda=\frac{c}{f}=\frac{299792458}{540\times10^{12}}=5.55\times10^{-7} \ m = 555 \ nm$

555 nm is yellow-green color, as can be seen from the table below:

1. The visible wavelength is around 380 to 700 nm

3.1. As can be seen from the table, the colors on the edge of the range are dark violet and nearly black.
