I saw other people getting 1.72 cm which is 0.0172 m but the the answered I wrote is what I got in the calculator so I'm not sure how they got thatehild said:Can it be correct? You see the bright fringes on the screen. Their distances is in the range of mm or cm, Can 10-13 m true?
actually Ehild was right I did not use parenthesis when I divided by 6.67x10-7 so the actual answer is 0.171 m.BvU said:Dear sudent,
you want to avoid this kind of disaster by estimating the outcome of a calculation before using an electronic calculator. In this case you divide 7.6 by 6.7 which is a little more than 1, and 10-7 by 10-6 which is 10-1.
Times 1.5 should give a little over 0.15. So your answer is 17.1 cm.
A diffraction grating is a device that consists of a large number of equally spaced parallel slits or grooves. When light passes through these slits, it is diffracted and produces a pattern of bright and dark fringes.
The distance between adjacent bright fringes, also known as the grating spacing, is calculated using the formula d = λ / sinθ, where d is the grating spacing, λ is the wavelength of light, and θ is the angle of diffraction.
The grating spacing is directly proportional to the number of slits. This means that as the number of slits increases, the grating spacing also increases.
The distance between the light source and the diffraction grating does not affect the pattern of fringes. However, it does affect the intensity of the fringes. As the distance increases, the intensity of the fringes decreases.
Yes, a diffraction grating can be used to separate different wavelengths of light. The grating spacing determines the angle at which each wavelength is diffracted, allowing for the separation of different wavelengths. This is known as spectral dispersion.
