79. Out of the following frequencies/ wavelengths has the most energy? a) 1x1012/s b) 1X10/s c) 1X104 m d) 1X107 m

science chemistry

Answer 1

Answer #1

The correct option regarding the most energy is

a) 1 x 10^12 /s

this is because energy is given by

E = hn where n is the frequency so

Energy is directly proportional to frequency while in case of wavelength it is

E = hc / $\lambda$

where $\lambda$ is the wavelength so energy is inversely proportional to wavelength.

which meant that frequency with magnitude of 10^12 /s has most energy.
