What property of a wave remains unchanged when a wave enters a different medium? 5 points amplitude frequency wavelength velocity

Frequency

Explanation:

The property of waves that remains unchanged as it crosses the boundary of one medium to another is the frequency of the wave.

As a wave moves from one boundary to another, the wavelength and the speed of the wave changes.

The speed of the wave is product of wavelength and frequency. Also, the wavelength of the wave is function of the distance between successive crests or troughs of a wave.

The frequency of a wave is the number of waves that crosses a medium per unit of time.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
