(a) Find a symbolic expression for the wavelength A of a photon in terms of its energy E, Planck's constant h, and the speed of light c. (Do not substitute numerical values; use variables only.)
(b) What does the equation say about the wavelengths of higher-energy photons?
O higher energy photons have shorter wavelengths
O higher energy photons have longer wavelengths
O energy and wavelength are not related
An atom has its electron in the energy level at - 1.2 eV. It absorbs a photon, which promotes the election to the -0.4 eV level. What is the wavelength (in meter) of this photon.
Round off the answer to 2 decimal places with scientific representation.
1.2) In a region of gas where the optical depth is 2.0, what percentage of photons can
escape without being scattered or absorbed?
