Vibrated Pattern
Vibrated Pattern
A string has a linear density of 6.60 10-3 kg/m and is under a tension of 245 N.?
A string has a linear density of 6.60 10-3 kg/m and is under a tension of 245 N. The string is 1.8 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown below in the drawing.
a) Find wavelength of the traveling wave
b) Find frequency of the traveling wave.
I already found the speed to be 192.7m/s.
v = sqrt(F/mu) = 192.7 m/s.
Without the picture, I can’t determine the wavelength, but it is dependent on how many nodes are in the standing wave pattern between the ends of the string. If n is the number of nodes between the ends, then the wavelength will be 2L/(n+1), where L is the length of the string.
Once you know velocity and wavelength, frequency is given by v = lambda*f.

Which ones are true and which ones are false?
1. A photon consists of vibrating electric and magnetic fields that move through space at the speed of light.
2. A wave model can explain many properties of electromagnetic waves.
3. Light as a stream of tiny packets of energy describes the photoelectric effect.
4. X-rays are included in the electromagnetic spectrum.
5. A microwave is an image that shows regions of different temperatures in different colors.
6. Noise is a set of notes that combine in patterns that are pleasing.
7. A(n) incandescent light is a light bulb that glows when a filament inside it gets white hot.
