The motion of ceiling fan

3. Which of the following is a method of energy transfer:

All of these

Radiation

Conduction

Wave motion

4. The maximum displacement from mean position is called:

Maximum height

Intervel

Time period

Amplitude

5. The vacuum all electromagnetic wave have the same

frequency

speed

amplitude

wavelength

6. Wave equation is defined as:

f = T?

f = V ?

V = 2f?

V = f?

7. The time period of mass attached with a spring can be calculated by:

T =2??g/L

T = 2??m/k

T = 2??L/g

T = 1/T

8. The waves in which particle of the medium vibrate parallel to the direction of waves are called

Electromagnetic waves

both b and c

Longitudinal waves

Transverse waves

9. At mean position of pendulum, the potential energy of the pendulum is:

Both a and c

Much more

Maximum

Minimum

1. Diffraction of wave can be observed clearly only when the size of slit or obstacle is nearly__________ to the wavelength of the wave:
Equal	Two times	None of these	Four times
2. The water waves after striking the hurdle will:
Reflect	Diffract	All a , b, c	Refract
3. It mass of bob o a simple pendulum is doubled, its time period.
become four times	remains same	is doubled	none of the above

None of these	Damped motion	SHM	Random motion
5. Formula for time period of spring mass system is represented by:
T = 1/2??m/k	T = 2? ?k/m	T = 2??m/k	T = 1/2??k/m
6. In CD presence of pits is indicated by:
0	2	3	1
7. The relation between v,f and? of a wave is:
vf=?	v=?/f	f? = v	v? =f
8. At extreme position potential energy of the pendulum is
