General wave properties Quiz (Theory)

( 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.

1. e wave speed   
2. The frequency .

( i ) V = lambda 

     speed = 2000 x  

    Speed = s ^ -1 .

( ii ) 1) 20 Hz –   Hz

        2 ) V = lambda .

         lambda   =  V  

         lambda   =   / 20,000

                 = m 

        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 /  

Television signals are included into
  are sent to
the satellites that the signal to satellites

The particles of the string   up and down,which is perpendicular to the   of motion of the wave.

1. They travel at the speed of travel in  
2. They are  waves.

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  

F = / 0.40
frequency =  Hz.         ( final answer ) 

( i ) the frequency : remains the

( ii ) the speed : will  

Number of   pass through a point in   second.

Wave   is the transfer of and will not cause any net movement of the   through vibration of . 

(i )       cm.

( ii )     V = lambda .

           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.
