The photograph at right illustrates the pattern that appears on a distant screen when coherent red light is incident on a mask with two identical, very narrow slits. The two slits are separated by a distance d.
Point C marks the center of the screen. Point X marks a point of zero intensity, and points Y and Z mark maxima.

- The below image shows the changing frequency, and therefore, wavelengths for light from a distant source. The image on the left shows the normal laboratory values of light absorbed from the spectrum. The image on the right shows a distant object in motion. What is the behavior of the object? O The light is red shifted and the object is moving away from Earth. O The light is blue shifted and the object is moving towards Earth. O The light is blue shifted and the object is moving away from Earth. O The light is redshifted and the object is moving towards Earth.arrow_forwardThe diagram at the right represents the interference pattern created by two water waves. The waves were created by two objects bobbing up and down in phase at the same frequency. Point P on the pattern is a distance of 36.9 cm from S1 and 61.5 cm from S2. Determine the wavelength (in cm) of the water waves.arrow_forwardReflection by thin layers.

During this displacement, 240 fringe reversals (formation of successive dark or bright bands) are counted. The light being used has a wavelength of 634.8 nm. Calculate the displacement AL. 39.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. µm A single ray of light is split into two rays by mirror M, which is called a beam splitter.
