Energy and Wave Phenomena Flashcard

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting kinetic energy to potential energy when lifting an object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a cart at the top of a ramp.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact, often converting kinetic energy into heat.

Front

What is internal reflection?

Back

Internal reflection is the phenomenon where light waves are reflected back into a medium instead of passing through, used in fiber optic cables.

Front

What are noise-canceling headphones?

Back

Noise-canceling headphones use destructive interference to reduce unwanted ambient sounds by creating sound waves that cancel them out.

Front

What is wave interference?

Back

Wave interference occurs when two or more waves overlap, resulting in a new wave pattern that can be constructive (amplifying) or destructive (diminishing).

Front

What is electromagnetic radiation?

Back

Electromagnetic radiation is energy that travels through space in the form of waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is wavelength?

Back

Wavelength is the distance between successive peaks of a wave, which determines the type of electromagnetic radiation.

Front

Which electromagnetic radiation has the shortest wavelength?

Back

X-rays have the shortest wavelength among common forms of electromagnetic radiation.
