Module 7
Mix
Mix
This is the term for when light bounces off of an object.
What is reflection?
Remember, refraction is any bending of light and this leads to splitting light into individual wavelengths
How many ways do we classify waves?
What are 2 ways?
They are electromagnetic and mechanical waves
Colors belong to this smaller spectrum on our overarching spectrum.
What is the visible light spectrum?
Visible and invisible light is classified by this.
What is wavelength?
Remember, invisible light is any and all electromagnetic radiation that we cannot see.
L1.
This wave is not actually a wave, but a format.
What is a standard wave?
This is the symbol representing wavelength in the wave speed formula.
What is lambda?
This is the vertical distance between a wave and the equilibrium position.
What is amplitude?
Remember, scientifically this is another word for "strength"
This image is a brain-created image that we see when no light rays pass through the location of the image.
What is a virtual image?
Remember, A real image is an image that is formed when light rays converge to form an image
200 EACH
These are the two types of telescopes that we covered in class.
What are radio and optical telescopes?
Remember, radio telescopes tell us the past and forecast the future. Optical telescopes tell us more of what is actually present.
L3.
This is the hottest star color.
What is blue?
Remember, the temperature range for these stars is around 35,000O Celsius.
This wave relies on matter to travel.
What is a mechanical wave?
Remember, mechanical waves need matter to move. That matter is mainly a medium.
Double
This is the distance between consecutive crests in a single wave
What is wavelength?
Remember, wavelength and frequency are inversely related.
This is the measurement from the center of a concave mirror to the focal point.
What is the focal length?
Remember, the optical axis is the EQUILIBRIUM POSITION of a mirror.
This is a light with multiple wavelengths, travels in multiple directions, without a constant distance between the corresponding crests of the waves.
What is incoherent light?
Remember, Coherent light is light of only one wavelength that travels in one direction with a constant distance between the corresponding crests of the waves
L2.
This object does not allow electromagnetic waves to transmit through them.
What is an opaque material?
This material allows light to freely transmit through it.
What is a transparent material?
Remember, the transparent material is only going to take the required amount of energy needed for transfer in the form of heat, so it can be inferred that the wave will lose "no" energy.
Water waves are in what shape?
What is a combination?
They are COMBINING longitudinal and transverse motions. Also, longitudinal waves are compression waves and move WITH the particles of disturbance. Disturbances with transverse waves move vertically at a 90 degree angle to our wave
This mirror creates a wide-angle view and curves outward
What is a convex mirror?
Remember, you are trading magnification for a greater field of view, causing your image to appear smaller. Know your 3 mirror types and their characteristics.
Double
Stars have can be this many colors.
What is 7?
listed from hottest to coolest: blue, blue-white, white, yellow-white, yellow, orange, and red. The temperature of stars range from 1,000°C (red) to 35,000°C (blue).
This wave's shape is shown as two transverse waves that travel side-by-side together and are at right angles to each other.
What are electromagnetic waves?
They are setting the force fields in motion at equal rates.
This is the object used to split white light into individual visible wavelengths.
What is a glass prism?
Remember, when all of your wavelengths are present at the same time, you will perceive visible white light. When none of them are present, you will perceive darkness.
Frequency is measured in this.
What are hertz?
Remember, wave speed is in m/s and wavelength is measured in m
This category on our electromagnetic spectrum possesses the longest wavelength.
What are radio waves?
You will need to know the order based on wavelength (shortest on left). Know what type of wave is larger or smaller than the others.
This is the year that Galileo challenged the Roman Catholic Church and began to prove that the Sun was the center of the solar system
What is 1609?
If a wave has a longer wavelength, what kind of frequency is the wave?
What is a low-frequency wave?
increasing temperature means that we are increasing energy. Waves with higher energy have higher frequencies. Waves that have higher frequencies will have SHORTER wavelengths
