A photon has 8.0 × 10–15 J of energy. Planck’s constant is 6.63 × 10–34 J•s.

What is the frequency of the photon?

1.21 × 1019 Hz
8.3 × 10–20 Hz
1.21 × 10–19 Hz
8.3 × 1020 Hz

Answer:

8.3 × 10 ^ -20 Hz

[tex]energy \: of \: a \: photon \: = \: \frac{h}{f} \\ f \: = \: \frac{h}{energy \: of \: a \: photon} \\ f \: = \: \frac{6.63 \times 10 ^{ - 34} }{8.0 { \times 10}^{ - 15} } \\ f \: = \: 8.29 \times 10 ^{ - 20} [/tex]

hopefully it makes sense :)

Answer:

A. 1.21 × 1019 Hz
