Question

For the following statements, select T-True, F-False. (If the first is T and the rest F, enter TFFFF.)

A) The Hubble Space Telescope can resolve blue light a little better than it can resolve red light
B) When white light strikes a prism, the red part of the spectrum gets bent to slightly larger angles than the blue part.
C) The wider the slit, the broader the diffraction pattern.
D) The light from two car headlights will form an interference pattern if shined onto a white screen.
E) Adding more lines to a diffraction grating, but keeping the distance between the lines fixed, makes the resulting pattern spread out more.

Explanation / Answer

A) F (higher the wavllength, better the resolution and red have highest wavelength)

B) F (higher the wavelength, lesser the bending)

C) F (The diffraction pattern becomes spread out when the slit becomes narrower.)

D) F (You will not see an interference pattern from the automobile headlights for two reasons. The first is that

the headlights are not coherent sources and are therefore incapable of producing sustained interference.

Also, the headlights are so far apart in comparison to the wavelengths emitted that, even if they were

made into coherent sources, the interference maxima and minima would be too closely spaced to be

observable.)

E) F ( As N increases, the pattern changes to narrow

maxima separated by wide dark regions)
