The diagram shows light passing through an opening and forming bands.

there is an incident beam of light toward an opening in a grating. the light breaks into 7 different paths labeled n = 3, n = 2, n = 1, n = 0, n = 1, n = 2 and n = 3.
which two order bands are the dimmest?

n = 0 and n = 1
n = 0 and n = 3
n = 1 and n = 2
n = 2 and n = 3

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
