Problem 2 (25 points) Figure shows Young's double-slit experiment with coherent light source wavelength of the light λ is 500 nm, the slit separation d is 025 mm and the slit-screen separi on 50 cm. Assume that θ is small enough to use the approximation sin θ tan θ (a) (15 points) Let's assume that there is a constant phase offset π (1800) between the lights after thesíts 1 and s2. What is the distance y on the screen between...
1. Light of wavelength 640 nm is incident on two slits separated by 0.880 mm. An interference pattern is observed on a screen 2.20 m away. a) Using the small angle approximation (tan θ sinθ), find the distance between the central maximum and the first bright fringe. b) What percent of error is made in locating of the seventh-order bright fringe if the small angle approximation is used compared to using the exact trigonometric function? c) How does the...

Peaks represent bright spots. The constructive interference when the distances from the first slit to the screen and the second slit to the screen differ by a whole wavel ength than The two angles labeled theta can be considered equal when the distance to the screen, D,...
1. If light with a frequency below the cutoff frequency for a certain metal hits that metal: Question 1 options: electrons will be ejected after the intensity of the light reaches a certain value no electrons will be ejected electrons will be ejected, but will fall back to the metal the light will be re-radiated by the metal I don't know. 2. One electron-volt is equivalent to Question 2 options: 1 J 1 V 1.6 x 10^-19 J 1.6 x...
shows the fringes observed in a double-slit interference experiment when the two slits are illuminated by white light. The central maximum is white because all of the colors overlap. This is not true for the other fringes. The m = 1 fringe clearly shows bands of color, with red appearing farther from the center of the pattern, and blue closer. If the slits that create this pattern are 25 μm apart and are located 0.95 m from the screen, what...
please answer both questions A soap film (n = 1.33) sits on top of a plastic plate (n = 1.37). White light strikes the film nearly perpendicularly. The smallest nonzero film thickness for which the film appears bright due to constructive interference is 153 nm. What color does the film appear? O Violet (420 nm) Yellow (580 nm) O Red (650 nm Blue (475 nm) O Green (500 nm) Question 16 5 pts Use the Bohr model to find the...
Light of wavelength 429 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.10 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). (a) Determine the distance y from the central bright fringe to the second-order bright fringe. (Hint: The diffraction angles are small enough that...
Light of wavelength 385 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.18 m. A diffraction pattern is produced on the screen that consists of a central bright fringe and higher-order bright fringes (see the drawing). (a) Determine the distance y from the central bright fringe to the second-order bright fringe. (Hint: The diffraction angles are small enough that...
A double-slit interference experiment is performed with two very narrow slits separated by 0.19 mm. The experiment uses red light with a wavelength of 700 nm and projects the interference pattern onto a screen 5.0 m away from the slits. (a) What is the distance between two nearby bright fringes on the screen? (b) What is the distance between two nearby dark fringes on the screen? Assume these fringes are all near θ = 0. A Young's double-slit interference experiment...
1. (10 points) Two identical speakers are continuously emitting sound waves uniformly in all directions at 440 Hz. The speed of sound is 344 m/s. Point P is a distance of rı= 3.13 m away from speaker 1 and r2 = 4.30 m from speaker 2: i. What is the phase difference between the waves at Point P? ii. Is this a point of constructive interference, destructive interference, or something in between? Explain. 2. (10 points) A real (non-ideal) double-slit...
