A+
How does TIR transmit information in an optical fibre? (2+ diagram) - CORRECT ANSWER-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˚?") - CORRECT ANSWER-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) - CORRECT ANSWER-force x perpendicular distance around a
pivot (1) between force and pivot (2)
define center of gravity - CORRECT ANSWER-the point in a body (1) where the weight of an
object appears to act (1)
state principle of moments - CORRECT ANSWER-for a body in equilibrium (1) the sum of
clockwise moments about a point (1) is equal to the sum of anticlockwise moments
, state the principle of conservation of momentum - CORRECT ANSWER-total momentum
before = total momentum after (1) in an isolated system (no external force)
state the relationship between the force acting on a body and the momentum of the body -
CORRECT ANSWER-force proportional to rate of change of momentum
