Question

calculate the frequency & energy of photon of light with wavelength 520nm​

Answer 1

Answer:

ok I will answer u soon

Step-by-step explanation:

just mark as brainliest

The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2.38 eV 

Answer 2

Answer:

$c = frequency \times wavelenth \\ \\ frequency = 3 \times {10}^{8} \div 520 \times {10}^{ - 9} \\ = 0.0057 \times {10}^{ 1 } \\ \\ energy = \frac{hc}{ 520 \times {10}^{ - 9} } \\ = 6.626 \times {10}^{ - 34} \times 3 \times {10}^{8} \div 520 \times {10}^{ - 9} \\ = .038 \times {10 }^{ - 17} joul$
