Most remote controllers for AV equipment emit radiation with the wavelength profile shown in the figure below. What is the energy of a photon that has a wavelength corresponding to the peak in the figure? Planck's constant is h = 6.626 ×× 10–34 J • s, and the speed of light is c = 3.00 × 108 m/s.

The blackbody radiation emitted from a furnace peaks at a wavelength of 6.0 x 10-6 m (0.0000060 m). What is the temperature inside the furnace? K Need Help? Read It

On a certain day, light is shining perpendicularly on the surface of the earth with an intensity of 713 W/m². Assuming that all the photons in the light have the same wavelength (in vacuum) of 733 nm, determine the number of photons per second per square meter that reach the earth. Enter your answer in scientific notation. If your answer is 5.14 x 104, input 5.14e+4 as your answer.

The figure at the right shows transitions between three states of a molecule (labeled E1, E2, and E3) that are observed through the emission and absorption of photons in a pair of experiments, A and B.1. Which transition is associated with the emission of the photon of the longest wavelength?a b c d e2. Which transition is associated with the absorption of the photon of the shortest wavelength?a b c d e   3. If a cold gas of these molecules was in the atmosphere of a star that was emitting a continuous spectrum, you would expect to see some dark lines across the continuous spectrum from that star. This is because the molecules in the atmosphere of the star absorb some of the light emitted by the star. Which frequencies would you expect to be significantly blocked by passing through the cold gas?a. (E2 - E1)/hb. (E3 – E1)/hc. (E3 – E2)/hd. None of them.a b c d
