Front 14

Doppler effect

Back 14

Change in wave frequency due to a moving wave source is the dropper effect.

Front 15

Refraction

Back 15

The beginning of a wave, caused by a change in its speed as it moves from one medium to another.

Front 16

Thermal energy

Back 16

Energy that comes from energy in an object has because, of the movement of its J atoms in molecules.

Front 17

Nuclear energy

Back 17

Energy in the nucleus or core as an atom.

Front 18

Electromagnetic

Back 18

Waves that contain electric and magnetic fields.

Front 19

Conductors

Back 19

Electric- current can flow freely.

Front 20

Insulators

Back 20

materials that impede the free flow of electrons from atom to atom and molecule to molecule.

Front 21

Thermal energy is both potential n kinetic energy?

Back 21

Both of them have atoms, molecule, electrons or particles. Thermal energy is both energies because, the molecules store potential energy and when they move kinetic energy happens.

Front 22

Explain, Thermodynamics in first law and second law?

Back 22

First law- energy can be changed from one form to another.

second law- states that the entropy of any isolated system not in thermal equilibrium almost always increases.

Front 23

Explain how thermal energy is transferred between objects through the process?

Back 23

Conduction, Convection and Radiation can use heat energy to heats earths surface.

Front 24

X-ray waves

Back 24

short wavelengths, high frequency

Front 25

Physical change

Back 25

rearranges molecules but, does not change. matter is altered without modifying its basic molecular composition.

Front 26

What are some physical properties?

Back 26

Texture, Density, and Shape.

Front 27

Mechanical waves

Back 27

a wave that is a osoliation of matter and therefore transfers energy through a medium

Front 28

How does sped of electromagnetic waves and how they warm your skin?

Back 28

Infrared radiation, is a type of electromagnetic waves that transmits heat and thermal radiation.

Front 29

How does solar energy warm our skin?

Back 29

Source of IR radiation, some of the solar energy travels at the speed of light. until it reaches a host. This host being your skin, this is why you feel the warmth of the sun. Our skin absorbs the IR radiation, warmth causes skin to vibrate quicker increasing kinetic energy and our skins temperature.

Front 30

Speed of light in a vacuum?

Back 30

3.00*10^8 m/s

Front 31

What makes the change in the frequency and wavelength different?

Back 31

The higher the frequency, the shorter the wavelength and vice versa.

Front 32

What are the several different types of electromagnetic waves?

Back 32

Microwaves, Radio waves, Infrared waves, visible light waves, Ultraviolet waves, X-ray waves and Gamma rays.

Front 33

How do electromagnetic waves heat the earth?

Back 33

Electromagnetic waves travel at about 3.0 x 10⁸ m/s in a vacuum and takes about 8 minutes for waves to reach earth.

Front 34

Where does the rest of the EM radiation go?

Back 34

EM radiation reaches earths atmosphere, some is absorbed and the rest continues to earths atmosphere.

Front 35

What happens to the UV radiation when it is emitted to earth?

Back 35

UV radiation is absorbed by the ozone layer and is re-emitted as heating the stratosphere.

Front 36

Hows does the presence of the Greenhouse gases contribute to amount of heat absorbed by our atmosphere?

Back 36

It reduces the amount of EM radiation emitted back out of the atmosphere and heat builds up even more.

Front 37

How can chemical energy be converted into electrical energy?

Back 37

Example- chemical energy in a battery is converted into electrical energy , the electrical energy which involves the motion of electrical charges or currents can be used to power everyday devices.

Front 38

Two types of mechanical waves?

Back 38

Tran-verse waves

Longitudinal waves

Front 39

Longitudinal waves/ Congressional waves

Back 39

Produce compression and rare-fraction when traveling through a medium.

Front 40

Wavelength

Back 40

Distance between one point on a wave and the nearest point on a wave.

Front 41

Frequency

Back 41

The number of wavelengths that pass a fixed point each second.

Front 42

How can you find the frequency of a transverse wave?

Back 42

Counting the number of crests that pass by a point each second.

Front 43

Wave speed

Back 43

Light waves travel faster than sound waves. seed depends on the medium it is traveling in.

Front 44

Amplitude

Back 44

Related to the energy the waves comes, more energy it has the more amplitude it will carry.

Front 45

Microwaves

Back 45

Subgroups called ¨bonds¨ and are what allow the waves to detect weather and track hurricanes.

Front 46

Radio waves

Back 46

Longest wavelength created by lightning or astronomical objects such as stars.

Front 47

Back 48

All electromagnetism is light but, this only portion of it that we can actually see with the naked eye.

Front 49

Ultra violet waves

Back 49

UV rays are on the spectrum between visible light and are only visible to some insects.

Front 50

Gamma rays

Back 50

The smallest and most energetic of all waves in the spectrum and are produced by the hottest objects.
