Question

what is the energy of photons that corresponds to a wave number of 5×10^-5 m^-1​

Answer 1

Answer:

$energy \: = h \times c \times v$

where , v is wave number .

h is plancks constant

c is speed of light .

$energy \: = 6.6 \div \times {10}^{ - 34} \times 3 \times {10}^{8} \times 5 \times {10}^{ - 5} \\ energy \: = 9.9 \times {10}^{ - 31} joules$
