Question

The wave disturbance is y= 0.02 os(π÷2+50πt)cos(10πx) speed of wave ,antinode and node at x=

Answer 1

Answer:

Wavelength and frequency

Light is measured by its wavelength (in nanometers) or frequency (in Hertz).

One wavelength

equals the distance between two successive wave crests or troughs.



Frequency (Hertz)

equals the number of waves that passes a given point per second.
