Question

6.32 A stellar object is emitting per second at this wavelength, what is the total energy of the photons radiation at 335 mm, if a detector on earth is capturing 33. detected in one hour? 10photons 6.41 In hydrogen, an electron transitions from n-3 to n cormesponding to this transition? electron transitions from n-3ton 2. What is the wavelength of the photon is the 2.35 Only two isotopes of copper eccur naturally. "Cu (atomic mass 62.9296 amuç abundance 69.17 %) and Oul atomic mass-6492 78 amuc abundance 30.83 %). Calculate the annk weght (average atomic mass) of copper 7.44 For the following pairs, indicate which element has the lower first lonication energy TI, Ba Ge, CI Adopted from 7.65: Write balanced equations f for the following reactions Potassium cxide and water Carbon dioxide and water

Explanation / Answer

6.32 )

We know that Energy of photons

E = nhc/

n = no of photons per second

h= planck's constant = 6.626 x 10-34 J.s

c = velocity of light = 3 x 108 m/s

= wavelength

Given that wavelength = 3.35 mm = 3.35 x 10-3 m

no of photons detected per second = 3.3 x 108

Therefore,

Total energy of photons detected in 1 hr = 1 hr x  nhc/

= [3600 sec x  3.3 x 108 /secx 6.626 x 10-34 J.s x 3 x 108 m/s ] /  3.35 x 10-3 m

= 70492 x 10-15 J
