Aphoton has a frequency of 2.9 × 10–16 hz. planck’s constant is 6.63 × 10–34 j•s. the energy of the photon, to the nearest tenths place, × 10–49 j.

Ans: E = 1.9 *10⁻⁴⁹ J

Given:

Frequency of photon, ν = 2.9 *10⁻¹⁶ Hz

planck's constant, h = 6.63*10⁻³⁴ Js

To determine:

The energy (E) of photon

Explanation:

Energy is related to the frequency by:

E = hν

   = 6.63*10⁻³⁴ Js * 2.9 *10⁻¹⁶ s-1

   = 1.9 *10⁻⁴⁹ J
