Science Chapter 8, 9, 10 Flashcards
What do we call the ability to cause change?
Energy
What do we call the transfer of thermal energy through electromagnetic waves ?
Radiant Energy
What is the process in which energy moves from one object to another without changing forms?
Energy Transfer
What is the measure of the average kinetic energy of the particles in a material?
Temperature
What is another name for stored energy?
Potential Energy
What is the transfer of thermal energy due to collisions between particles?
Conduction
What is the sum of potential and kinetic energy in a system?
Mechanical Energy
What do we call the conversion of one kind of energy into another kind of energy?
Energy transformation
What is another name for energy due to motion?
Kinetic Energy
What do we call the transfer of thermal energy by the movement of particles from one part of a material to another?
Convection
What do we call energy from between the bonds of atoms?
Chemical Energy
What kind of disturbance transfers energy without transferring matter?
A Wave
What do we call energy applied over a distance?
Work
What do we call energy from the nucleus of an atom?
Nuclear Energy
What is the top part of a transverse wave called?
The Crest
In which part of a longitudinal wave are the particles of the medium closest together?
Compression
What kind of wave moves perpendicularly to the disturbance that creates it?
Transverse Wave
What occurs when light travels through an object?
Transmission
What is the name given to a material though which a wave travels?
A Medium
Which kind of waves can travel through matter and space?
Electromagnetic Waves
What do we call the bottom part of a transverse wave?
Trough
Which kind of waves can only travel through a medium?
Mechanical Wave
What do we call it when energy from a wave travels into a material?
Absorption
What do we call it when a wave slows down as it goes from one medium to another?
Refraction
What do we call it when a wave bounces off of a surface?
Reflection
What do we call a surface that forms an image by regular reflection?
A Mirror
What do we call a region of a longitudinal wave where the particles of the medium are farthest apart?
Rarefaction
Fifteen waves pass a position in five seconds. What is the frequency?
Three Hertz
Which kind of wave moves parallel to the disturbance that creates it?
Longitudinal
Sound is which kind of wave?
Mechanical/Longitudinal
Which part of the eye controls how much light can enter the eye?
The Iris/ Pupil
What do we call the lens made of transparent tissue located on the outside of the eye?
The Cornea
What do we call the area on the back of the eye containing light sensitive cells?
Retina
What is the law of reflection?
The angle of incidence equals the angle of reflection.
What happens when you increase the amplitude of the sound wave?
The Sound Gets Louder
What do we call the distance between the crest of one wave to the crest of the next?
Wavelength
What do we call the number of oscillations a wave makes per second?
Frequency
What does the law of conservation of energy state?
Energy is neither created nor destroyed; only transformed from one form to another.
What happens when the frequency of a sound wave increases?
The Pitch Increases
Glass is an example of what kind of material?
Transparent
What is the SI unit for loudness?
Decibel
What do we call something we cannot see through?
Opaque
