Sound
Sound waves are this type of mechanical wave.
Longitudinal
Visible light is a small portion of this spectrum.
Electromagnetic
The ancient Greeks called naturally occurring magnets this.
Lodestones
This famous scientist discovered that radium emitted strange rays she called radioactivity.
Marie Curie
This famous scientist gave us the designations positive (+) and negative (-) to describe electrical charges.
Benjamin Franklin
The frequency of the sound wave corresponds to this sound quality.
Pitch
Bending light when it travels at an angle from one transparent medium to another is called this.
Refraction
The circular path that electrical current flows through is called this.
A circuit
This type of reaction involves splitting heavy atoms like uranium to produce energy.
Nuclear fission
According to his uncertainty principal you can’t know both the speed and location of a particle.
Werner Heisenberg
The loudness of a sound is measured in these units.
Decibels
This famous scientist showed that light can behave as both a particle and a wave.
Albert Einstein
This is how hard it is for electricity to move through a conductor and is measured in ohms.
Resistance
This type of reaction involves combining light elements like hydrogen to produce heavier elements.
Nuclear fusion
Electromagnetic waves with the lowest frequency are called this.
Radio waves
Sounds with frequencies above 20,000 Hz are called this.
Ultrasonic or ultrasound
This type of lens is thicker in the middle and thinner around the edges.
Convex
This type of charging occurs when a charged object comes near neutral object
Charging by induction
These Greek letters are used to designate the 3 types of radioactivity.
Alpha, Beta & Gamma
Electrical potential is usually referred to as this.
Voltage
This part of the ear converts vibration into electrical impulses that can be sent to the brain.
Cochlea
Thomas Young performed this famous experiment showing light behaved like a wave.
Double slit experiment
This Scottish scientist showed that electricity and magnetism are two sides of the same force he called electromagnetism.
James Clerk Maxwell
Fusion reactions typically use these two isotopes of hydrogen.
Deuterium & Tritium
Marie Curie discovered these two radioactive elements.
Radium & Polonium
