The wave equation says that a waves speed is equal to its wavelength times its what?

frequency for apex learners not speed :)


What effect if any does increasing the speed of the plunger have on the wavelength of the waves?

It will shorten the wavelength.


How does this speed change as the slinky is stretched?

As the slinky is stretched, the speed at which the waves travel through it decreases. This is because the tension in the slinky increases, leading to a slower propagation of the waves. The relationship between the speed of the wave and the tension in the medium is described by the wave speed equation.


What equations tell us how fast a wave travels?

The speed of a wave can be determined by the equation: speed = frequency x wavelength. This equation relates the speed of a wave to its frequency and wavelength. Additionally, the wave equation, c = λf, where c is the speed of light, λ is the wavelength, and f is the frequency, can be used to determine the speed of electromagnetic waves in a vacuum.


What is the relation between the frequency wavelength and speed of a sound wave?

The speed of a sound wave is determined by its frequency and wavelength through the equation: speed = frequency x wavelength. This means that as frequency increases, wavelength decreases, and vice versa, to maintain a constant speed.


Does the equation for calculating the speed of a wave not apply to light waves?

There are several equations relating the speed of a wave to other parameters. Let us call the speed of a wave v. The following equations are true for ALL waves, including (but not limited to) sound waves, water waves, electromagnetic (light) waves, and waves on a string like on a guitar:v = l * fHere l is the wavelength of the wave and f is the frequency. Imagine a bunch of ripples of water, or the graph of the function sin(x). The distance between two peaks in these cases is the wavelength. The frequency of a wave is the number of wavelengths created per unit time. Another equation which describes the speed of a wave is called, appropriately, the wave equation. This equation is a differential equation, which means that it relates a function F to a "rate of change" of itself. For example, the speed of an object is the rate of change in the object's position. See the Wikipedia article describing the wave equation.Now light waves are special kinds of waves because they are the only kind of wave that can propagate through empty space (ignoring quantum mechanical waves). In empty space (vacuum), light ALWAYS travels at the speed of light (really?!), or 180,000 miles per second. This is not true for other kinds of waves (sound waves need to propagate through matter like air or metal, water waves need to propagate through water [SURPRISE], and it doesn't take a genius to realize that waves on guitar strings actually need the strings in order to exist).


If the waves are going by at the same frequency the wave that has the greatest speed will have the greatest?

The wave with the greatest speed will have the greatest wavelength. This relationship is governed by the wave equation: speed = frequency x wavelength. Therefore, if two waves have the same frequency and the speed is greater in one wave, then its wavelength will be greater as well.


What is the speed at which a wave travels?

The speed at which a wave travels depends on the medium through which it is traveling. In general, the speed of a wave is determined by the frequency and wavelength of the wave, according to the equation: speed = frequency x wavelength.


How does the speed of radio waves compare with the speed of infrared waves?

Radio waves travel at the speed of light, which is the fastest speed possible in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.


What is the speed of the waves if the wave period is 4 seconds?

The speed of a wave is determined by the equation: speed = wavelength / period. Without knowing the wavelength, it is not possible to calculate the speed based solely on the wave period.


How the wave length of waves traveling with the same speed would change if the frequancy of the waves increased?

If the frequency of waves traveling at the same speed increased, the wavelength of the waves would decrease. This is because wavelength and frequency have an inverse relationship when wave speed remains constant, as described by the equation: speed = frequency x wavelength.


Predict how the wavelength of waves traveling with the same speed would change if the frequency of the waves increased?

If the frequency of the waves increased, the wavelength would decrease. This is because the speed of the waves is constant in a given medium, and the wavelength and frequency of a wave are inversely proportional to each other according to the wave equation v = λf.
