Question

is this correct?

Compared to a photon with 1 = 50 nm, a photon with 2 = 500 nm has a lower frequency more energy O a higher speed in a vacuum. o a shorter wavelength

Answer 1

Ans. a lower frequency

Explanation:

Frequency, $\nu$ = hc/$\lambda$

$\lambda$ = wavelength

Hence, from the formula, frequency increases when wavelength decreases and vice-versa.

So when wavelength increases from 50 nm to 500 nm , the frequency will decrease in second case.

Frequency = hc / 50nm .......in first case

Frequency = hc/ 500 nm ......in second case

Hence case 2nd has lower frequency.
