How does the color white show
When the sun reflects all the light
When a wave bends after it enters a different material.
Refraction
amount of thermal energy it takes to increase the temperature of 1 kg of material by 1 degree Celsius
specific heat
increase in a material's volume when the temperature is increased
thermal expansion
a device that regulates the temperature of a system
thermostat
How does the color black show
When the sun color absorbs all the light
Is it possible for a light ray to both reflect and refract?
Yes
transfer of thermal energy from one material to another by electromagnetic waves
radation
the average kinetic energy of the particles that make up a material is
tempature
The energy stored in the interactions between objects or particles is
potential energy
When a wave bounces of a barrier or a border between 2 different materials.
Reflection
Does light speed up or slow down in denser materials?
Slows down
the transfer of thermal energy between materials because of collisions between the particles is
conduction
the movement of thermal energy from a warmer object to a cooler object is
heat
decrease in a material's volume when the temperature is decreased
thermal contraction
Does light bend toward or away from the normal in denser materials?
Toward
Which refracts more: higher or lower frequency light?
Higher frequency (shorter wavelength).
The sum of kinetic energy and potential energy in the particles that make up a material is
thermal energy
machine that converts thermal energy into mechanical energy
heat engine
device that converts electric energy to thermal energy
heating appliance
When light enters a denser medium, which wavelengths refract more: the shorter wavelengths or the longer wavelengths?
Shorter wavelength (higher frequency).
When white light enters a prism, which color refracts (bends) the most: red or violet?
Violet because it has a higher frequency, which means a shorter wavelength.
