EXAM WITH MULTIPLE CHOICE COMPLETE QUESTIONS AND
ANSWERS/VERIFIED/ GRADED A+/GUARANTEE PASS (JUST
RELEASED!!!!!)
Effect on diffraction pattern when wavelength decreases (3) -
----Answers---Maxima closer together (1) angle decreases (1)
smaller path difference (1)
What happens when white light is used in slits instead of
monochromatic light? (4) - ----Answers---Central bright
fringe (maximum) is white (1)
Fringes on either side are continuous spectra (1)
Dark fringes would be closer together due to λred being larger
than the average λwhite (1)
Bright fringes (maxima) are wider
How do diffraction patterns (fringes on the screen) form? - ---
-Answers---Interference (1)
from light from two slits overlapping (superposition) (1)
maxima where crests meet (constructive interference) (1)
dark fringes/minima form where crest and trough meet
(destructive interference) (1)
Formation of a stationary wave - ----Answers---Two waves
superpose (1)
same wavelength and/or frequency (1)
, Travelling with equal and opposite velocity (direction of
movement) (1)
stationary vs progressive waves (3 for each) - ----Answers--
-stationary: have nodes/antinodes (1) points between nodes all
in phase (1) cannot transfer energy
progressive: no nodes/antinodes (1) within one wavelength all
points are out of phase (1) can transfer energy
How does TIR transmit information in an optical fibre? (2+
diagram) - ----Answers---Core has higher refractive index
than cladding (1) when incident light at a greater angle than
critical angle of cladding TIR occurs (2)
Observations of a polarisation filter rotation? ("What
observations could be made when the filter in rotated through
360˚?") - ----Answers---Variation in intensity between
maxima and minima (light and dark) (1)
Two maxima and Two minima within 360 (1)
define moment of a force (2) - ----Answers---force x
perpendicular distance around a pivot (1) between force and
pivot (2)
define center of gravity - ----Answers---the point in a body (1)
where the weight of an object appears to act (1)
