A velocity and wavelength
Explanation:
When a periodic wave travels from one medium to another, its velocity and wavelength changes in the process.
A periodic wave is a wave with repeating pattern.
- When a wave crosses different medium with different densities, their velocity and wavelength changes.
- This implies that wave causes disturbances in different ways.
- This change in wavelength and velocity as a wave crosses two medium is known as refraction.
- When a wave moves from a less dense medium to a denser one, the velocity reduces and the wavelength increases.

<span>Two sound waves of equal amplitude interfere so that the compression of one wave falls on the rarefaction of the other. The statement which is true is that A. no sound is heard.
These waves interfere, which means that their equal amplitudes match and thus cancel each other out, which is why there is no sound.

AnswerA tell me what u got sorry if its worng
Explanation:
Answer: 8000N
Explanation: since it is frictionless that means it has 100% efficiency therefore the mechanical advantage is 1 meaning the load equals to the effort
Parallax arises due to change in viewpoint occurring due to motion of the observer, of the observed, or of both.
