A diffraction grating is to be used to find the wavelength of the light in the emission spectrum of a gas. The grating spacing is not known, but a light having a known wavelength of 554 nm is deflected by 44° away from the central maximum in the second order by this grating. The light of the wavelength to be measured is deflected by 42° away from the central maximum in the second order. What is the wavelength of this light? Light of wavelength 574 nm passes through two slits separated by 0.651 mm and produces an interference pattern on a screen 5.98 m away. The intensity at the central maximum is lo. What is the distance on the screen, in mm, from the center of this central maximum to the point where the intensity due to double-slit interference has fallen to 1/2 lo? An object 4.9 mm tall is placed 22 cm from the vertex of a convex spherical mirror. The radius of curvature of the mirror has a magnitude of 56 cm. What is the height of the image, in mm?
