4.0 x 102 m? use the equation e-
intion hc
, where hc = 1.99 x 10-25 j•m.
o a. 8.0 x 10-23
o b. 2.0 × 1027
o c. 6.0 x 1025 j
o d. 5.0 × 10-28 j

D.

Explanation:

The energy of an electromagmetic wave is given by:

Where:

is the Planck constant

is the speed of light in vacuum

Then

is the wavelength
