What is the First Law of Thermodynamics |
|
Definition
Whenever heat flows into or out of a system, the gain or loss of thermal energy equals the amount of heat transferred |
|
|
Term

|
Definition
conduction-objects make contact convection- circular motion of hot and cold in a fluid radioaction- electro magnetic energy |
|
|
Term

Term
What is the major difference between a mechanical and electromagnetic wave? |
|
Definition

|
Definition
|
|
Term
Example of electromagnetic wave |
|
Definition
|
|
Term
Two types of mechanical waves and their differences |
|
Definition
Transverse- the wave moves perpendicular to the direction of the energy (spring) Longitudinal- the wave moves parrallel with the direction of the energy |
|
|
Term
What is rarefaction and compression |
|
Definition
occurs in longitudinal waves, rarefaction is the rarity of a wave due to stretching and compression is the squeezing together of part of a wave |

|
Definition
|
|
Term

|
Definition
|
|
Term
Why does the same pitch on different instruments not sound the same? |
|
Definition
Every central pitch resonates background pitches in multiples of two, every instrument has different intensitys of these multiples |
|
|
Term
|
Definition
the point where crests and troughs cancel each other out/ cross over on a wavelength |
|
|
Term
Why do we see lightning before we hear thunder? |
|
Definition
Velocity of light is significantly greater than the velocity of sound |
|
|
Term
Two types of interference? |
|
Definition
constructive- crest to crest/trough to trough destructive- crest to trough |
|
|
Term
Why are tsunamis so small in deep water and then jack up in shallow water? |
|
Definition
because in deep water the amplitude of the crest is tiny because the wave length is so long, but then the shallow water causes the wave to move upwards and increases the amplitude |
