How could you use the diffraction of a laser beam by a slit to determine the wavelength of the laser light?
The light pattern of the image formed in a screen placed far after the slit will give you the answer, but you need to know the slit width and have to measure the distance to the screen.
It is easier to use the interference pattern of two slits to get an accurate measurement

A new laser color has just landed at ThinkGeek and we like what we see. Red and even green lasers are now fairly common but blue lasers not so much. So, if you want to have the latest fashionably cool laser color this year, we've got you covered. This laser outputs light in the 405 nanometer wavelength which produces a very unique blue-violet color beam, that is unusual for a handheld pointer. This is also the same wavelength used in Blu-ray DVD players. The shorter wavelength allows more data to be stored than on a standard DVD which uses a red laser (650 nanometer). This laser is certainly awesome but it's also useful for applications such as biomedical instrumentation, imaging, spectroscopy, laser induced fluorescence sensing, microscopy. And if you're not into any of those activities, then this laser can be used to write on photoluminescent material like our Glow Graffiti.

Using an ordinary patch cord with MMF, 1000BASE-LX/LH GBICs, and a short link distance (10s of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the Cisco 1000BASE-LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).

You have a laser with wavelength (λ) 640 nm. You shine it through a diffraction grating of 400 lines per millimeter. You measure the distance to a screen to be 20.3 cm. You measure the second dot in millimeters from the center dot.
What is the wavelength of the laser light?
__________________[nanometer].
Use three significant figure or N/A if not enough information is given.
Trick question.
The output wavelength from the diffraction will be the same as the input.
