Consider a diffraction grating with a grating constant of 500 lines/mm. The grating is illuminated with a monochromatic light source of unknown wavelength. A screen is placed a distance 1.24 m away and the 1st order maxima is measured to be a distance 38 cm from the central maxima. What is the wavelength of the light expressed in nm?

Hi, can I please get some help with this question? Thank you!

A diffraction grating has a grating constant of 415 lines/mm. If composite light with wavelengths of 601 nm and 461 nm are incident upon the grating, what is there angular separation in the 1st order spectrum? Answer this with a positive number of degrees.

A single slit with a slit width of 0.48 mm is illuminated with monochromatic light having a wavelength of 491 nm. At what distance away should a screen be placed so that the central maxima has a spatial width of .52 cm. Express the distance in meters.

Angel is experimenting with a diffraction grating of unknown spacing. He is looking to determine the wavelength of the light in the emission spectrum of a gas and finds that a light having a known wavelength of 623.1nm is deflected by 43.8 ° away from the central maximum in the second order by this grating. Light of the wavelength to be measured is deflected by 45.4° away from the central maximum in the second order. What is the wavelength of this light in nanometers? Please give your answer as a whole number.

Light with wavelength 2 passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distance d from the middle of the central maximum. Calculate the wavelength of light if D=2.4 m, d =1 mm and w = VAD.Give your answer in nanometers. Answer: Choose...

Red light of wavelength of 635nm is used in a diffraction grating experiment. The first bright fringe was formed at y1= 70 cm from the zeroth order on a screen that is located at L= 2m away from the diffraction grating. What is the spacing distance (d) in meters of this diffraction grating?

There is a circular slit with its radius a = 0.1mm. The distance between the slit plane and detector plane is given by R=1m. Roughly estimate the requirement of the wavelength of incident light for Fraunhofer diffraction with appropriate justification.
