When a string fixed at both ends is vibrated, it can produce standing wave in the string at certain frequencies called harmonic frequencies. For nth mode of harmonic, standing wave has n - number of loops in the string and the frequency is given by: ...

Step 2: Calculate the linear mass density (μ) The linear mass density (μ) is defined as the mass per unit length: μ=ML Substituting the values: μ=80×10−3kg10m=8×10−3kg/m Step 3: Substitute values into the wave speed formula ...
The Wave Equation If you choose a point in a medium through which a wave is propagating, the period of the wave is the time it takes that point to oscillate back to its original position. Dividing this number into 1 yields the number of times the point oscillates each second, which is ...
The maximum speed of a motor is mainly determined by its characteristics and the power supply voltage. However, it is also affected by the carrier frequency of the PWM control, which is set by the IC. For sinusoidal PWM drive, the rec...
A linear wave number can also be described in terms of the wave's velocity (v) and frequency (f), as they relate to its wavelength. Velocity refers to the wave's speed and is measured in meters per second (m/s). Frequency refers to the number of wave cycles per second and is meas...
Long story short: darkness isn’t a wave itself because it isn’t anything, if it has a speed it’s the same as light speed, and also light is profoundly weird stuff (and not to be taken lightly). The ocean, desert, basket, and hypnotic pictures are from here, he...
