[-/1 Points] DETAILS WAUNIPHYSAV1 36.P.007. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Red light (660 nm) falls on a single slit (0.500 mm width) and makes a diffraction pattern on the wall 2.00 m away. (a) What is the location of the first dark fringe? m (b) What is the width of the central maximum? m 3. [-/1 Points] DETAILS WAUNIPHYSAV1 36.P.014. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER When a single slit is illuminated with monochromatic light with a wavelength of 500 nm, the distance between the second and fourth minima in the diffraction pattern on a screen 55.0 cm from the slit is 3.00 mm. Determine the width of the slit. 4. [-/1 Points] DETAILS WAUNIPHYSAV1 36.P.017. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Find the angle for the third-order maximum for 552 nm wavelength light falling on a diffraction grating having 1550 lines per centimeter.5. [-/1 Points] DETAILS WAUNIPHYSAV1 36.P.020. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER For a lab practical, your TA provides you with a piece of plastic that has 445 lines per cm and a monochromatic light source with a 550-nm wavelength. If the light is incident perpendicular to the plane of the plastic, determine the distance between the bright regions on a screen 1.95 m away. cm 6. [-/1 Points] DETAILS WAUNIPHYSAV1 36.P.026. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Light from a helium source is incident perpendicular to a diffraction grating with 4125 lines per centimeter. The visible helium spectrum is bracketed at the short wavelength end by a violet line with a wavelength of 402.6 nm and at the long wavelength end by a red line with a wavelength of 667.8 nm. For this spectrum, determine the following. (a) the number of orders of this spectrum that include the entire visible spectrum (Enter a whole number.) (b) the angular separation between these two lines for the second order of the spectrum 7. [-/1 Points] DETAILS WAUNIPHYSAV1 36.P.032.
