6 a) White light shines into a prism and forms a spectrum on a screen. What effect, if any, would
you see if a red filter were placed in the path of
the white light?
[2]
b) Would it make any difference if the filter were
placed at the other side of the prism near the
screen?
[1]
c) The screen is changed to a green one. What might

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
