Wave motion (1)

the time to reach the 6 amplitude is ……

• 0.25 T

• 0.5T

• 1.5 T

A pendulum moves a periodic time “  $\frac{3}{2}$   T ” from rest point ,makes a displacement ………  

• Half Complete oscillation

• 1.5 complete oscillation

• Zero

The time taken from A to B is ….. The time taken from B to C .

• smaller than

• Longer than

• As same as

If the frequency is 0.05 Hz, the displacement done in time 30 second starting the motion from B is …….

• 4 cm

• 0.08 m

• Zero

• 8 m

If the time of a max. displacement is 2 S, so the frequency is ………..

• 0.125 Hz

• 8 Hz

• 0.1 Hz

all of the following are units of frequency except ………

• Wave/ sec.

• sec^-1

• cm^-1

• Hz

If the ratio between the periodic time and the frequency is 625 s², so the time of 3 oscillation is....

• 75 s

• 150 s

• 25 s

if the time taken from “ B” to “ A” is 5 second

Find frequency ……

• 0.05 Hz

• 20 Hz

• 5 Hz
