frequency is given as f=c/L, where c is the speed of light and L is the wavelength of the electromagnetic wave. Using c=3*108 m/s, we get
3*108/(550*10-9)=545*1012Hz=545 THz
Remember that Hz=1/seconds such that units fit
The energy is E = hf=hc/r = .3636E-18 joules or 2.2727 electron volts.
Mn has 550 Nm
The wavelength is 436 nm.
Photon energy is proportional to frequency ==> inversely proportional to wavelength.3 times the energy ==> 1/3 times the wavelength = 779/3 = 2592/3 nm
Twice the energy means twice the frequency, and therefore half the wavelength.
The energy of the photon is 3,1631.e-19 joule.

Energy per photon is proportional to frequency. That tells us that it's alsoinversely proportional to wavelength.So if Photon-A has wavelength of 400-nm, then wavelength of Photon-Bwith twice as much energy is 200-nm .

The wavelength is 610 nm.
The wavelength is 435,62 nm.
