Question

part (a) in the simulation, choose the 'slits' window. select the laser icon, and choose the 'two slits' option. click the 'screen' box, it may help to quantify the positions of the peaks by clicking 'intensity'. set the 'slit width' to the lowest setting (200 nm), and increase the light source amplitude to the maximum value. set the barrier location to roughly half the distance between the light source and the screen. finally, set the slit separation to 1750 nm. what happens in the simulation if you move from blue light to orange light? choose 3 correct answers. the distance from the central maximum to the first fringe increases. the distance from the central maximum to the first fringe decreases. more fringes appear on the screen. fewer fringes appear on the screen. the distance between bright fringes increases. the distance between bright fringes decreases. unanswered part (b) use the same initial set up as given in the previous question. using violet light, what happens in the simulation if you increase the distance between two slits? choose 3 correct answers. the distance from the central maximum to the first fringe increases. the distance from the central maximum to the first fringe decreases. more fringes appear on the screen. fewer fringes appear on the screen. the distance between bright fringes increases. the distance between bright fringes decreases. unanswered part (c) use the same initial set up as given in the previous question. using violet light, what happens in the simulation if you move the two slits closer to the screen (i.e. decrease l by moving the barrier further to the right)? choose 3 correct answers. the distance from the central maximum to the first fringe increases. the distance from the central maximum to the first fringe decreases. more fringes appear on the screen. fewer fringes appear on the screen. the distance between bright fringes increases. the distance between bright fringes decreases.

Answer 1

In the simulation, if you move from blue light to orange light, the distance from the central maximum to the first fringe will increase, more fringes will appear on the screen, and the distance between bright fringes will decrease.

Step-by-step explanation:

In the simulation, if you move from blue light to orange light, the correct answers are:

1. The distance from the central maximum to the first fringe will increase.
2. More fringes will appear on the screen.
3. The distance between bright fringes will decrease.

In the simulation, if you increase the distance between two slits using violet light, the correct answers are:

1. The distance from the central maximum to the first fringe will increase.
2. More fringes will appear on the screen.
3. The distance between bright fringes will increase.

In the simulation, if you move the two slits closer to the screen using violet light, the correct answers are:

1. The distance from the central maximum to the first fringe will decrease.
2. Fewer fringes will appear on the screen.
3. The distance between bright fringes will decrease.
