1.
A sound-absorbing surface is
steel plate
polished tile
curtain fabric
glass
2.
An echo is heard 0.40 s after a shout. The cliff is how far away? (v = 340 m s−1)
136 m
272 m
34 m
68 m
3.
On an oscilloscope, a taller wave shows a
louder sound
faster sound
longer wavelength
higher pitch
4.
A wave has period 5.0 ms. Its frequency is
5 Hz
20 Hz
200 Hz
2000 Hz
5.
Low-frequency sounds are heard round corners better because they
travel faster
are louder
have larger amplitude
have long wavelengths and diffract more
6.
Double glazing reduces noise because
it traps a layer of air that reflects and absorbs sound
it makes sound travel faster
glass is hot
it blocks light
