This point on the screen is bright dark neither very bright nor very dark the distance between the slits needs to be known to determine whether it is bright, dark, or in between. The image formed by a camera should always be real and at the film. Show all work and justify all answers. A diamond is submerged in water. Light from within the water is incident on the diamond at the angle as shown in the figure below.
White light passes through the grating.
Define interference, and explain how it applies to this diffraction grating example. A microscope has a 1.8X objective lens which has a 85 mm diameter, and a 3.5X eyepiece lens which is 14 cm from the objective. In the picture below, I have drawn the inverted image produced by the objective lens. Finish the picture by drawing the ray diagram for the eyepiece, and identifying the final image seen through the microscope.
