Front

What occurs when the trough of one wave overlaps the crest of another wave?

Back

Destructive interference occurs, causing the new wave to have less energy than the original waves.

Front

What is a renewable energy resource?

Back

Wind is a renewable energy resource.

Front

What do solar cells convert into electricity?

Back

Solar cells convert sunlight into electricity.

Front

What does conduction involve in terms of energy transfer?

Back

Conduction involves the transfer of thermal energy due to the movement of particles.

Front

Which type of power plant is most directly affected by droughts?

Back

Hydroelectric power plants are most directly affected by droughts.

Front

Define destructive interference in wave behavior.

Back

Destructive interference occurs when two waves overlap in such a way that their amplitudes cancel each other out, resulting in a wave of lower amplitude.

Front

Define constructive interference in wave behavior.

Back

Constructive interference occurs when two waves overlap in such a way that their amplitudes add together, resulting in a wave of greater amplitude.

Front

What is the primary source of energy for solar power?

Back

The primary source of energy for solar power is sunlight.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., wind, solar), while non-renewable sources cannot be replenished in a human timescale (e.g., coal, oil).

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is a measure of the kinetic energy of particles.
