Waves
What is the relationship between frequency, wavelength, and wave speed
Wave speed = Frequency
what type of Electromagnetic wave has the shortest wavelength and highest frequency
Gamma rays have the shortest wavelength and highest frequency
What does Newton's first law of motion state
an object at rest stays at rest
what are four common states of matter
solid liquid gas plasma
what is the primary source of enery for the earth
the sun
What is the difference between constructive and destructive interference?
Constructive interference occurs when waves combine to create a larger amplitude, while destructive interference occurs when waves combine to create a smaller amplitude or cancel each other out
which type of Electromagnetic wave is used in microwaves?
Microwaves are used in microwave ovens
what is the relationship between force, mass, and acceleration according to Newton's second law?
force is equal to mass times accelertion
in which state of matter do particles have the most energy
plasma is the state of atter inwhich particles have the most energy
which form of energy is associated with the movement of atoms and molecules
thermal energy
What is the Doppler effect?
It is the change in frequency or wavelength of a wave in relationto an observer who is moving relative to the wave source
what is the range of Electromagnetic radiation that is visible to the human eye called?
this range is called visible light
Wha does Newton's 3rd law of motion state
it states that for every action, there is an equal and opposite reaction
Describe the arrangement and movement of particles in a solid
In a solid, particles are tightly packed in a fixed arrangement. They vibrate in a place but do not move around freely
what type of energy is stored in the bonds of chemical compounds
chemical energy
what is the highest point of a wave called
The crest
which type of Electromagnetic wave is used in medical X-rays?
X-rays are used in medical imaging
if an object is not accelerating, what can you conclude about forces acting on his 4th law
if an object is not accelerating forces acting on its 0
what is required for a liquid to change into gas
For a liquid to change into a gas (a process called vaporization, evaporation, or boiling), it requires the addition of heat energy
name the process by which plants convert light energy into chemical energy
photosynthesis
what is the phenomenon that occurs when a wave bends as it passes from one medium to another
the phenomenon is called refraction
what is the order of the spectrum from lowest to highest frequency?
Radio waves, microwaves, infrared, visible light,x-rays, and Gamma rays
how does newtons 2nd law explain why it is harder to accelerate a heavier object compared to a lighter one?
shows that for the same force a larger mass will result in smaller acceleration
what is the difference between boiling and evaporation?
boiling occurs at a specific temp the boiling point and through out the entire liquid
what is the SI unit of energy
Joule
