( i ) m . ( final answer )
( ii ) As the time period of the one is constant, the is constant.
( i ) Not uploaded in the presentation.
( ii ) inverted.
( i ) A joining these points on the of the waves.
( i ) V = lambda
speed = 2000 x
Speed = s ^ -1 .
( ii ) 1) 20 Hz – Hz
2 ) V = lambda .
lambda = V
lambda = / 20,000
Wavelength = cm. ( final answer )
amplitude = mm
( ii ) Place a cork on top of , as the passes, the cork will gain energy and move and down.
( iii ) A is a line that the points in .
i ) frequency = 1
= 1 /
frequency = Hz
( ii ) time s. ( final answer )
Difference : The of the waves are .
Similarity : The waves are waves.
Wave motions are and downwards .
accelerations that carry .
no net movement of the .
Speed = x 10 ^ 8 ms ^ -1 ( final answer )
( i ) V = lambda .
V = 2 x
Speed = cm s ^ -1 ( final answer )
wavelength = cm. ( final answer ).
Use the stopwatch to find the to complete .
find the frequency = 1 /

are sent to
the satellites that the signal to satellites
wavelength = m.
( i ) wavelength = cm
( ii ) V = lambda .
Speed = x 11 cm
Speed = cm / s ( final answer )
i ) V = [ multiply by ] [ times ]} lambda .
2 = f x

Speed = 5 x
= cm s ^ -1 ( final answer )
( i ) frequency : of complete per second.
( ii ) Wavelength is the length of the .It can be found by finding between two neighbouring .
( i ) The wavelength will , the wave must travel a distance at the same time.
( i ) In waves the oscillations are along the direction of the .
the are perpendicular or 90 degrees to the direction.
( ii ) A speaker is used to sound.
The microphone is connected to a .
Place a chamber to hold CO ^ 2 in between the and the microphone.
