Which of the following statements about the 3rd overtone of a vibrating air column of an open pipe is correct? It has

Consider the wave equation:  \(y =  10sin(x - 50t)\), What does the number 10 represent?

Plane waves through a narrow gap emerge as circular waves. This phenomenon is known as

A ray of light incident at an angle \(\theta\) in a rectangular prism grazes the surface of the prism on emerging from the prism. Determine the value of the angle. [Absolute refractive index of the material of the prism is 1.5] 

The diagram above illustrates a wave setup between two fixed ends 4.0m apart. If the speed of the wave is 1.0\(ms^{-1}\), its wavelength and frequency respectively are
