Red laser light of wavelength 650 ?? shines on a CD, which has tiny notches for each byte of information stored on the CD. You see that the distance between the 0th order bright spot and the 1st order bright spot is 26 ?? projected on the wall that is 60 ?? away from the CD.
Determine the spacing between the notches on a CD.
Determine the notches per millimeter on a CD.
You repeat the experiment with a DVD, which has a much higher data storage capacity (more notches per mm). Would you expect the 1st order bright spot to be closer or farther away from the 0th order spot for the interference pattern of the DVD?

A laser emits light at a wavelength of 488 nm at an average power of 5.00 mW. The laser’s produces a circular beam with a diameter of 1.00 mm. This light is then passed through a double slit projecting an interference pattern on a screen 2.25 m away. a. (10 points) If the central bright fringe is 3.50 cm wide, what is the spacing between the slits?

1-A parallel beam of light from a laser with a wavelength 450 nm, falls on a grating whose slits are 1.28 x 10-4 cm apart. How far (in cm) is the 1st order bright spot from the center of the pattern on a screen 3.4 m away? 2-A grating whose slits are 3.2x10-4 cm apart produces a third-order fringe at a 25.0° angle. What is the wavelength of light that is used?

A helium–neon laser produces light with a wavelength of 638 nm. When this light is shone through a double slit apparatus, an interference pattern is produced on a screen 2.0 m away, with the distance between the first and seventh nodal lines being 5.0 cm. (a) Determine the distance between the slits. (b) What is the maximum number of bright fringes that could possibly appear on the screen?

Two narrow slits are illuminated by a laser with a wavelength of 514 nm. The interference pattern on a screen located x = 4.60 m away shows that the third-order bright fringe is located y = 9.00 cm away from the central bright fringe. Calculate the distance between the two slits. 7.88×10-3 cm You are correct. Previous Tries The screen is now moved 1.1 m further away. What is the new distance between the central and the third-order bright fringe?...

In the physics we have Helium-Neon lasers that produce a wavelength of 632 nm. Suppose that we have a diffraction grating that is unlabeled (so we don’t know its slit spacing) and a violet laser pointer whose wavelength we wish to determine. We then shine the Helium-Neon laser on the grating, project the diffraction pattern onto a screen that is 1.00 m from the grating and measure the positions of the diffraction maxima on the screen. Next we remove the...

Laser light of wavelength 480 nm is incident on a circular aperture which has a diameter of 0.011 mm. A diffraction pattern is observed on a screen which is placed 94 cm from the aperture. Give your answer to at least three significant figures. Answer must be accurate to 1%. diffraction angle, θ, of the first diffraction minimum: 3.051662 degrees You are correct. 1) What is the distance, on the screen, from the center of the central bright spot to the...
