To find the wavelength of a spectral line using a diffraction grating, you can use the formula: dsin(θ) = mλ, where d is the spacing of the grating lines, θ is the angle of diffraction, m is the order of the spectral line, and λ is the wavelength of the light. By measuring the angle of diffraction of the spectral line and knowing the grating spacing, you can calculate the wavelength of the light.

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.
Which waves can be separated into different wavelengths of colored light?
Visible light waves can be separated into different wavelengths of colored light. This can be achieved using a prism, diffraction grating, or other optical devices that disperse light based on its wavelength, resulting in the familiar rainbow spectrum.
Visible light from a distant star can be spread into a spectrum by using what?
A prism or a diffraction grating can be used to spread visible light into a spectrum. These optical components work by causing the different colors of light to bend by varying amounts, producing the characteristic rainbow pattern.

What observations indicate that visible light has a wavelength much shorter than a centimeter?
Answer #1:The colored pattern seen in a soap bubble & The colored pattern seenwhen light passes though a diffraction grating.================================Answer #2:The fact that you can see small things ... and small details on big things ...that measure much less than a centimeter. You can't see the edges of thingsthat are smaller than whatever you're using to explore them with.As an analogy:In principle, you could get a picture of the size and shape of your computer byshooting small beans at it, and gathering data of which beans bounce off of it,and in what direction they bounce. But you couldn't get the same picture byshooting large beach-balls at it.
Determation of wave lenght using diffraction grating?
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.
Why able to see different colors through a spectroscope?
A spectroscope works by dispersing light into its component colors using a prism or diffraction grating. Each color corresponds to a different wavelength of light, allowing us to see the distinct colors present in the light source. This phenomenon is known as spectral dispersion.
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.
How can you observe the spectrum in the lab?
You can split white light using a prism or a diffraction grating.
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 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).
How do you break white light without a prism?
You can break white light without a prism by using a device called a diffraction grating. A diffraction grating has thinly etched lines; you can see this effect by noticing the rainbows you see from the bottom of a DVD.

Which is a correct way to measure wavelength?
One correct way to measure wavelength is by using a ruler or measuring tape to measure the distance between two consecutive points on a wave, such as between two peaks or two troughs. Another correct way is to use specialized equipment like a spectrophotometer or a diffraction grating to measure wavelengths of light.
How visible spectrometer works?
A visible spectrometer works by separating light into its different wavelengths using a diffraction grating or prism. The light is then directed onto a detector which measures the intensity of each wavelength. This data is used to create a spectrum, showing the distribution of wavelengths in the light source.
