The wavelength of a photon that has an energy of 7.53* 10^-32

= 2.64 × 10^7 m

Explanation:

Energy is given by the formula;

E = hc/λ

Where h is Planck’s constant (= 6.626 x 10^-34 Js), c is the speed of light (3.00 x 108 m/s) and λ is the wavelength in meters.

Therefore, wavelength will be given by;

λ = hc/E

  = (6.626× 10^-34 × 3 × 10^8)/(7.53 × 10^-32)

  = 2.64 × 10^7 m

the answer is b. dilution
