The wavelength of light can be determined using a diffraction grating by measuring the angles of the diffraction pattern produced by the grating. The relationship between the wavelength of light, the distance between the grating lines, and the angles of diffraction can be described by the grating equation. By measuring the angles and using this equation, the wavelength of light can be calculated.

How do you calculate wavelength from diffraction grating?
You can calculate the wavelength of light using a diffraction grating by using the formula: λ = dsinθ/m, where λ is the wavelength of light, d is the spacing between the grating lines, θ is the angle of diffraction, and m is the order of the diffracted light. By measuring the angle of diffraction and knowing the grating spacing, you can determine the wavelength.

Can white light be separated only by a prism?
No, white light can also be separated into its component colors using a diffraction grating or refracting telescope.
What is diffraction grating and how is it constructed?
A diffraction grating is an optical component with a series of closely spaced slits or grooves that diffract light into its individual wavelengths. It is typically constructed by etching these slits or grooves onto a flat surface of glass or a reflective coating using techniques such as photolithography or holography. The spacing and geometry of the slits determine the dispersion properties of the grating.
What is the approximate wavelength of a light whose second-order dark band forms a diffraction angle of 15.0 when it passes through a diffraction grating that has 250.0 lines per m?
Using the equation for diffraction grating: (sin(θ) = mλ/d), where (m = 2) (second-order dark band), (\theta = 15°), and (d = 1/250.0\ m), we can solve for the wavelength (\lambda). Rearranging the equation gives (\lambda = d × sin(θ) / m). Plugging in the values: (\lambda = (1/250.0) × sin(15°) / 2 ≈ 2.4 × 10^{-7}\ m).

Velocity of ultrasonic wave using acoustic grating?
The ultrasonic waves generated with the help of a quartz crystal inside the liquid in a container sets up standing wave pattern consisting of nodes and anti-nodes. The nodes are transparent and anti-nodes are opaque to the incident light. In effect the nodes and anti-nodes are acts like grating(a setup of large number of slits of equal distance) similar to that of rulings in diffraction grating. It is called as acoustic grating or aqua grating. Hence, by using the condition for diffraction, we can find the wavelength of ultrasound and thereby the velocity of sound in the liquid medium.
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
Using a mercury lamp instead of a sodium lamp in a plane diffraction grating experiment might result in a different wavelength of light being emitted. This would affect the interference pattern observed on the screen, leading to a shift in the position of the fringes. Additionally, the intensity of the light and the overall visibility of the interference pattern might also be altered.

What is the spectum of light bent into a circle?
A spectrum of light bent into a circle would appear as a rainbow ring, with the different colors of light arranged in a circular pattern. This effect can be seen in nature, such as in a rainbow, or can be created artificially using a prism or diffraction grating.
What is a correct way to measure wavelength?
One correct way to measure wavelength is by using a spectrophotometer or a spectrometer, which can provide precise measurements of the electromagnetic spectrum. Another way is by using diffraction grating or interferometer techniques to determine the distance between wave crests. Finally, wavelength can also be calculated using the formula: wavelength = speed of light / frequency.
