The dissociation energy of a molecule is the energy required to break apart the molecule into its separate atoms. The dissociation energy for a particular molecule is 1.12 × 10-18 J. Suppose that this energy is provided by a single photon.

Determine the (a) wavelength and (b) frequency of the photon. (c) In what region of the electromagnetic

(a) 1.78 * 10^(-7) m

(b) 1.69 * 10(15) Hz

(c) Ultraviolet light

Explanation:

(a) To determine the wavelength, we use one of the formulae of energy of a wave:

E = hc/λ

Where h = Planck's constant

c = speed of light

λ = wavelength.

Therefore, wavelength, λ, is:

λ = hc/E

λ = (6.626 * 10^(-34) * 3 * 10^8) / (1.12 * 10^(-18))

λ = 1.775 * 10^(-7) m

This is the wavelength of the photon.

(b) Using formula for speed of a wave, we can find the frequency:

c = λf

Where f = frequency.

f = c/λ

f = (3 * 10^8) / (1.775 * 19^(-7))

f = 1.69 * 10^(15) Hz

This is the frequency of the photon.

(c) By comparing the frequency and wavelength of the photon with the electromagnetic spectrum, the proton is in the region of ultraviolet light.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
