Problem 38.4: Wavelength of light through a single slit

slit width: μm

Please wait for the animation to completely load.

This animation models light hitting a single slit. You can change the width of the slit and use the protractor to measure angles (position is given in centimeters and angle is given in degrees). Restart. What is the wavelength of the light?

We have made the higher-order diffraction patterns easier to see by brightening them (since the higher-order terms are very dim).
