Explain the Resonance of Sound in Strings
Strings on musical instruments, like harps, are held still at both ends, that is why the standing waves have nodes at every end of the string. The lowest natural frequency of the string's sound is known as the fundamental frequency. The wavelength of the primary frequency is equal to two times the length of the string.
While playing guitars and violins, the length of the vibrating part of the string can be altered with finger placement. Several frequencies of sound - that is, several notes - can be acquired as you change the length of the vibrating part of the string.
Define the Ray Diagrams for Lenses When drawing ray diagrams for thin lenses, we can assume that the lens is infinitely thin. Instead of considering refractions at each surface o
It has large energy gap 3.0ev and is regarded as high temperature semiconductor. It is extremely refectory subliming in the region of 2800 0 C. Because of large band gap it is hope
