13 A teacher demonstrated the photoelectric effect by illuminating a zinc plate with
electromagnetic radiation.
When ultraviolet radiation of wavelength 320 nm was incident upon the zinc plate,
electrons were emitted from the zinc surface.
When visible light of wavelength 420 nm was incident upon the zinc plate, no effect was
observed.
Explain these observations. Your answer should include calculations.
work function of zinc = 3.74 eV

4 * 1 Air molecules are trapped in a container by a piston, as shown.
piston
The position of the piston is adjusted so that the volume available to the air molecules is
reduced. The temperature of the air stays constant.
Explain how the pressure exerted by the air changes. You should refer to the motion of
the air molecules.

16 The closest distance from the eye where light from an object can be brought to a focus
is known as the near point distance. The near point distance for a human eye is taken to
be 25 cm.
A long‑sighted eye has a near point distance greater than 25 cm. This may cause
problems with focusing on near objects.
A converging lens can be used to correct this problem. The converging lens forms an
image of a near object at the actual near point distance of the long‑sighted eye.
(a) State the type of image formed by the converging lens when used to correct a
long‑sighted eye.

(b) (i) It is claimed that 1% of the ice would melt if the ice sculpture were in direct
sunlight continuously for 12 hours. Assume that radiation, of intensity I , from
the Sun is directly incident upon the top of the sculpture, as shown below.
I = 1350 W m
Deduce whether this claim is correct.
initial temperature of ice sculpture = – 20 °C
intensity of the Sun = 1350 W m

(b) Tall buildings sway in the wind. The design of the Petronas Towers permits safe
movement of the towers.
(i) The towers were designed to permit a maximum horizontal displacement of
0.90 m at the top of the towers. The natural frequency of each tower is 0.17 Hz.
Calculate the maximum velocity at the top of one of the towers when the tower
is oscillating at its natural frequency.
