Question

Pis

Calculate the energy of one photon of yellow light that has a wavelength
of 398 nm.
O 5.00 x 10-19 J
O 2.75 x 10-17)
O 6.17 x 10-8
O 1.46 x 10-26)
O 5.04 x 10-12

Answer 1

5.00×10-19 J

Step-by-step explanation:

E = hv

but v = c ÷ wavelength

E = (6.626×10-34) × ((3×10^8)÷(398×10-9))

= 4.9945×10-19

≈5.00×10-19
