The bending of waves as they pass from one medium to another is called:

• Reflection

• Refraction

• Diffraction

• Interference

Answer explanation

Refraction is the bending of waves as they pass from one medium to another, making it the correct choice in this context.

If two waves meet in phase, they will:

• Cancel each other out

• Increase in amplitude

• Decrease in frequency

• Not affect each other

Answer explanation

When two waves meet in phase, they will increase in amplitude due to constructive interference, reinforcing each other.

The rate of doing work or the rate of energy transfer is called:

• Power

• Force

• Momentum

• Velocity

Answer explanation

Power is the rate of doing work or the rate of energy transfer, making it the correct choice in this context.

Waves that require a medium through which to travel are called:

• Electromagnetic waves

• Mechanical waves

• Transverse waves

• Longitudinal waves

Answer explanation

Mechanical waves require a medium to travel, unlike electromagnetic waves. Transverse and longitudinal waves are types of mechanical waves.

The gravitational force between two objects depends on their masses and the _______ between them. (Fill in the blank)

• speed

• distance

• volume

• density

Answer explanation

The correct choice is 'distance' because the gravitational force between two objects decreases as the distance between them increases.

A parallel circuit is characterized by:

• A single path for current flow

• Multiple paths for current flow

• Decreasing resistance with more components

• Increasing voltage with more components

Answer explanation

A parallel circuit is characterized by multiple paths for current flow, allowing the current to split and flow through different branches simultaneously.

Which is NOT a type of potential energy?

• Elastic

• Kinetic

• Chemical

• Gravitational

Answer explanation

Kinetic energy is the energy of motion, not a type of potential energy. Elastic, chemical, and gravitational energies are all forms of potential energy.
