I had a couple of questions on the topic of Waves-Sound and Light.

1. What is the source of all waves?
*Vibration*

2. In one word, what is it that moves from source to receiver in a wave motion?
*Energy*

3. Does the medium in which a wave travels move with the wave?
*No*

4. What is the relationship among frequency, wavelength and wave speed?
*wave speed=wavelength * frequency

This question looks familiar. Didn't I answer it already? #3 is wrong.

By the way, with light, there is no "medium". Light will go through a vacuum.

To answer these questions, we first need to understand the basic concepts of waves - sound and light.

1. "What is the source of all waves?"
The source of all waves is vibration. Waves are created when an object or medium vibrates, causing a disturbance that travels through a medium or space.

2. "In one word, what is it that moves from source to receiver in a wave motion?"
The one-word answer is "energy." In wave motion, energy is what is transferred from the source to the receiver. As the disturbance caused by the vibrations moves through the medium or space, it carries energy with it.

3. "Does the medium in which a wave travels move with the wave?"
No, the medium in which a wave travels does not move with the wave. The particles of the medium oscillate or vibrate back and forth as the wave passes through, but they do not permanently move in the direction of the wave. For example, in a sound wave, the air molecules vibrate back and forth as the sound waves pass through but do not get carried along with the wave.

4. "What is the relationship among frequency, wavelength, and wave speed?"
The relationship among frequency, wavelength, and wave speed can be expressed by the equation: wave speed = wavelength * frequency. The wave speed refers to how fast the wave is traveling through the medium, wavelength measures the distance between two corresponding points on the wave (such as two crests or two troughs), and frequency represents the number of complete waves that pass a given point in one second.

Knowing any two out of the three variables (wave speed, wavelength, and frequency), you can calculate the third using the equation mentioned above. For example, if you know the wavelength and frequency of a wave, you can find the wave speed.
