9. Young's Double-Slit Experiment

Question 1

What is Young’s Double-Slit Experiment?

Answer 1

Young’s Double-SLit Experiment is a way to see two-source interference with light.

Question 2

What was the aim of Young’s Double Slit Experiment?

Answer 2

To Prove that light could both Diffract (through the two narrow slits) and intere (to form the interference pattern on the screen).

Question 3

How is Young’s Double Slit experiment carried out?

Answer 3

A laser of monochromatic and coherent light is shined through a mounted card containing two slits of the same size.
the length of the distance between fringes is then measured as well as the distance to the screen, to get an equation which links the wavelength, slit seperation, distance and fringe spacing.

Question 4

What are some safety precautions to carry out when doing the Young’s Double-Slit Experiment?

Answer 4

1. Never Shine the laser towards a person
2. Wear Safety goggles
3. Avoid shining the laser beam at a refractive surface
4. Have a warning sign on display
5. Turn the laser off when it’s not needed

Question 5

What safety precautions are actually needed when doing in a school environment

Answer 5

1. Don’t shine laser in other’s eyes
2. make sure environment is clean to remove tripping hazards in low light environment
3. point laser towards a wall when conducting the experiment.
