Illustrate the wave interactions of reflection, refraction, diffraction, and interference.

THE BASICS

  • Reflection is the throwing back by a body or surface of light, heat, or sound without absorbing it.
  • Refraction a phenomenon of light, radio waves being deflected in passing through the interface of mediums.
  • Diffraction is the process by which a beam of light or other system of waves spreads out as a result of passing through a narrow edge.

Interference is two or more electromagnetic waveforms to form a resultant wave in which displacement is either reinforced or canceled.

Low frequency radio waves, the human body is quite transparent. (You can listen to your portable radio inside your home since the waves pass freely through the walls of your house and even through the person beside you!) As you move upward through microwaves and infrared to visible light" this is how the four components play into make a solar powered radio.

"Malaysia receives enough energy from the Sun to generate 11 years worth of electricity." By gaining 11 years of electricity, solar powered radios would have a huge impact. I say this because this is basically what our project is promoting. Solar energy is better for the environment because it pollutes the air less and puts out less greenhouse gases.

Compare waves (mechanical, electromagnetic, and surface) using their characteristics to determine those produced by you device. (Angelique Shackleford)

MECHANICAL

  • An mechanical wave is a wave that is not capable of transmitting its energy through a vacuum (empty space). Mechanical waves requires a medium in order to transport through energy from one place to another.
  • Without the mechanical wave we wouldn't be able to hear the sound from the device.

ELECTROMAGNETIC

  • Electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (empty space). They are produced by the vibration of charged particles.
  • The characteristics of the Electromagnetic Wave it determines whether the power source is capable of working. With using a solar panel we will need the electromagnetic wave to power the source. Without it it wouldn't be able to power on.

SURFACE WAVES

  • A surface wave is a wave in which particles of medium undergo a circular motion. In a surface wave it is only, the particles at the surface of medium that undergo a circular motion.
  • Without the surface waves the product will be stuck on one volume. This is how the characteristics of the surface wave determines what is produced from the device

SUMMARY OF WAVES

  • The mechanical wave is unable to travel through a vacuum. The examples of this wave is a sound wave.
  • Then the Electromagnetic wave is able to travel through a vacuum. As explained the example of this wave is a light wave.
  • The surface wave is basically a wave that has to have particles of medium to undergo a circular motion.

After defining what the different waves are, what is the difference between them after being compared?

Another way to categorize waves is on the ability or inability to transmit energy in a vacuum (in this case is described as a empty space). But overall the difference between the three different waves is that, one has to do with sound the other light and lastly one that has to do with actual waves.

Out of all the waves I feel that all three will have the an effect. With having to build a solar powered radio we would need the concepts from both of the waves.

Using everyday examples to classify waves as transverse or longitudinal.
(Peyton Beaman)

TRANSVERSE WAVES

  • Transverse waves are what people actually think of when they think of a wave. Transverse wave is a moving wave that contain oscillations occurring at a right angle to the direction of the energy transfer.
  • Transverse wave is a moving wave that contain oscillations occurring at a right angle to the direction of the energy transfer.

A real life example of a transverse wave would be a row of people holding hands. When the farthest person to the left jumps, the rest of the people that are holding hands also jump because it pulls on their hand. The people move up and down while the wave moves left and right. A crowd waves is another example, or a guitar string.

LONGITUDINAL WAVES

  • Longitudinal waves are when the particles move parallel to the waves direction of travel. Longitudinal waves have compression and rare fraction. Compression is where density of the medium is the highest. Rare fraction is when the density of the medium is the lowest.
  • Unlike the transverse wave, a real life example of a longitudinal wave is a row of people. When one person bumps into another person, the next person bumps into the next person and so on.

WATER WAVES

  • Water waves are transverse because the water moves up and down while the wave moves over the surface. Also light and other electromagnetic waves are considered transverse waves. A sound wave is longitudinal because the sound bounces down the line. Another example would be a wave or a primary wave, because they push and pull. They can also be called compressional waves.

What is the law of conservation of energy?

The law of conservation of energy is a complex system of physics that states that the entire sum of energy stays constant if it's in a isolated system. It also states that energy can't be created or destroyed, but it can be transferred from one object to another.

What is kinetic and potential energy?

Potential and kinetic energy are the two types of energy that relate to motion. Potential energy is stored energy that is able to change relating to an object's position and condition. Kinetic energy comes from potential energy that is transferred to an object and allows it to move. Kinetic energy is the energy something has due to the motion of an object.

Where do we see the conservation of energy if life and how will it help power our solar radio?

As an example lets say you throw up a ball, it leaves your hand with a set amount of kinetic energy. At its peak it has no kinetic energy, but it has potential energy that was equal to the kinetic energy when it first left your hand. When you catch it it has the same kinetic energy when it left your hand. Solar energy is going to be converted into electrical energy for the solar powered radio. It is going to be able to work efficiently and effectively resulting in less electrical being used.
