Results

#1. Progressive wavw with doubly periodic motion means

form of the wave repeats itsself and travel equal distance in equal interval of time

repetition at equal distance

repetition after equal intervals of time

repetition in medium without interia

#2. A pulse on the string is inverted , when it is reflected from

a fixed end

a free end

both free as well as fixed ends

neither a fixed nor a free end

#3. At nodes , the velocity of stationary wave is

zero

maximum

minimum but not zero

#4. The example oisf forced vibration

resonance

beats

interference

diffraction

#5. Pleasing sounds are produced

in open organ pipe

in closed organ pipe

in both close and open pipe

in string indtruement

#6. The string of a sonometer is plucked so as to make it vibrate in one segment . the sound produced is called

first harmonic

first overtone

second harmonic

second overtone

#7. Loudness can be increased by

increasing distance

resonance

decreasing intensity

decreasing amplitude

#8. A series of notes separated by fixed musical intervals constitude

melody

overtone

musical scale

note scale

#9. Energy is not carried by which of the following waves.

stationary waves

progreesive waves

transverse waves

electromagnetic waves

#10. Resonance occurs when

a body vibrate at a frequency lower than its normal frequency

a body vibrates atb a frequency higher than its normal frequency

a body is set into vibrations with its natural frequency by another body vibrating with the same frequency

a body is made of the same materials as the sound source

#11. On increasing the temperature , the frequency of note emitted by an organ pipe

increases

decreases

remains unchanged

cannot be determined

#12. An organ pipe closed at one end has fundamental frequency of 1500 hz . the maximum number of overtones generated by this pipe which a normal person can hear is

#13. If vabration of a string are to be string increased by a factor of two , then tension in the string must be made

half

twice

fourtimes

eight times

#14. Beats are produced due to

diffraction

superposition

polarization

refraction

#15. When two sound waves are superimposed , beats are produced when they have

different amplitudes and phases

different velocities

different phases

different frequencies

#16. The loudness and pitch of a sound depends on

intensity and velocity

frequency and velocity

intensity and frequency

frequency and number of harmonics

#17. The waves set up in a closed pipe are

longitudinal and progressive

transverse and prigressive

transverse and stationary

longitudinal and stationary

#18. The fundamental frequency of a closed organ pipe of length 20 cm is equal to the second overtone of an organ pipe open at both the ends . the length of organ pipe open at both the ends is

80 cm

100 cm

120 cm

140 cm

#19. In sonometer experiment , the bridges are separated by a fixed distance . the wire which is slightly elastic , emits a tone of frequency 'n' when held by tension ' t' . if the tension is increased to '4t' , the tone emitted by the wire will be of frequency

slightly greater than 2n

slightly less than 2n

#20. It is possible to recognize a person by hearing is voice even if he is hidden behind a solid wall . this is due to the fact that his voice

has definite pitch

has a definite quality

has a definite capacity

can penetrate the wall
