When two waves of same type propagate along a straight line, but in opposite directions, their superposition upon each other gives a resultant wave which does not travel either way with time is called stationary wave. Define wavelength. Wavelength of a wave is the distance travelled by the wave during a periodic time.
Why is the wooden box of sonometer hollow? A hollow wooden box may enclose air which vibrates in resonance and increases the intensity of sound. Define node. In a stationary wave, point where zero amplitude is called node. Define antinode. In a stationary wave, the points where maximum amplitude is called antinodes.
What is the distance between two consecutive nodes or antinodes? Define beats. The phenomenon of regular variation in the intensity of sound with time at a particular position, when two sound waves of nearly equal frequencies, superimpose on each other is called beats. What is a fundamental note? It is a note of the lowest frequency. What are overtones? Overtones are notes whose frequencies are simple multiples of the fundamental notes. What is meant by unison? Two notes of same frequency are said to be in unison.
Define pitch. Pitch is a characteristic of musical sound, which distinguishes a sharp sound from a dull sound. How does the loading or filling at the prongs of a tuning fork affect its frequency? The frequency of the tuning fork decreases by loading and increases by filling at the prongs.
To find the relation between frequency and length, for a constant tension, frequency and diameter of a stretched string. Sonometer, slotted weights, tuning forks of known frequencies, rubber hammer, paper rider, steel wire, etc.
The sonometer consists of a long hollow wooden box with a peg at one end and a vertical pulley at the other end. One end of the experimental wire is attached to the peg and the other passes over the pulley. To keep the wire under tension, a suitable weight is suspended at the free end of the string by a weight hanger. Two movable bridges A and B are provided for the purpose of altering the vibrating length of the wire. Students have checked the complete Class 11 Physics Lab Manual in pdf for the great score in the final examination.
You can visit all these important topics by clicking the links given. The scholarships recognize merit and talent of students.
Students may apply for the Scholarships at the beginning of the academic year. Absolutely not, Class 11 Computer Science is definitely easier than its counterparts like Maths, Physics and Chemistry. It totally depends upon your interest and educational background. If you want a quick answer, take PCB i f you want to study medicine after Take PCM if you want to pursue engineering after Take both PCMB if you are not sure what you want to study.
If you like to do courses in basic sciences, then you can choose your preferred subjects accordingly. It depends on your aptitude and what you like. A better comparison would usually be topics within the subject itself.
But if you were to compare subjects, a better comparison would be between subjects like Biology and Biotechnology, Zoology and Botany, or Math and Physics.

That means, magnetism and electricity are so closely related to each other. The concept of this can be applied in many technologies for an effective productivity.
The study of this lab revolves around the generation, propagation and reception of mechanical waves and vibrations. These concepts embody the study of tiny subatomic particles or lightening fast speeds. They find applications in technologies such as atomic energy or semiconductors. It explains the study of optical properties for different material by adopting laser devices and handling basic aspects of interferometry. It also gives the dynamics of special type of non-linear systems.
