) (to the nearest integer)
Two identical strings made of the same material have their fundamental frequencies are and
respectively. Then the ratio
What will come in place of the question mark (?) in the following number series?
31, 58, 165, 644, 3195, ?
Wave motion:
Wave motion is defined as a form of disturbance transferred from one point to another involving transfer of energy but no transfer of matter.
Ex. A sound wave, water waves, a wave on a string.
The simplest types of wave motion are vibrations of elastic media, such as air, crystalline solids, or stretched strings. If, for example, when the string of the guitar is plucked and let's say a piece of paper is placed on it then the piece of paper will oscillate perpendicular to the direction of wave motion (energy or disturbance transfer).
Particles in wave motion do not travel, they only oscillate about their position.
A wave is a form of energy or momentum that travels due to disturbances produced.
