1. Calculate the wavelength in nanometer of yellow light of frequency 5.4 x 104 Hz, it speed of tight is 3 lac km/sec.​

Answer 1

Explanation:

The frequency (f) and wavelength (d) are related by the equation f = c/d, where c is the speed of light (approximately 2.99 x 10^8 meters per second). A specific yellow light might be 570 nanometers in wavelength, therefore, (2.99 x 10^8)/(570 x 10^-9) = 5.24 x 10^14. The yellow light's frequency is 5.24 x 10^14 Hertz.
