Astanding wave is a wave that appears fixed or stationary in space.

true or false

The given statement is true.

Explanation:

Standing wave is a stationary wave. It oscillates in time. But the peak amplitude does not move in space.

This is the wave which appear to be vibrating vertically.

When the amplitude is minimum at a point then that point is called node.

When the amplitude is maximum at a point then that point is called anti node.

Therefore, the given statement is true.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
