Light is shone on a diffraction grating with d= 1.00*10^-6 m. The second-order (m=2) maximum occurs at an angle of 74.6 degrees. What is the wavelength of the light IN NANOMETERS? nm

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.
