Polarization can be observed

for all types of waves.

for light waves.

for short wavelengths.

only at night.

The correct answer is "for light waves".

Explanation:

Transverse wave: the particles vibrate perpendicular to the direction of the propagation of the wave. For example, light wave.

Polarization specifies the geometrical orientation of the oscillation. It is the characteristic of all transverse wave. If the oscillation takes place in random direction then the light is said to be unpolarized light.

Therefore, polarization can be observed for light waves.

explanation:

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
