Waves
Does a wave with a bigger wavelength have more or less energy?
Less energy!
At what point in the pendulum does it have the most potential energy?
At the top!
What is the wave with the lowest energy and frequency?
Radio waves!
How many color receptors do we have in our eyes?
What is the trough on a wave and what is a crest?
A trough is the lowest point on a wave while the crest is the highest point on a wave!
Does a wave with a smaller wavelength have a higher frequency?
Yes!
At what point in the pendulum does it have the most kinetic energy?
At the bottom!
What is the wave with the highest energy and frequency?
Gamma rays!
What are the different color receptors in our eyes?
Red, green, and blue!
What is the equilibrium on a wave?
The horizontal line in the middle of a wave!
Which type of wave causes the medium to move perpendicular to the direction of the wave?
Transverse!
Does gravity affect the pendulum?
Yes! With less gravity it will go faster and the opposite with more gravity!
What is the wave with the biggest wavelength?
Radio waves!
What is reflection, refraction, and absorption?
Reflection: When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light.
Refraction:Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.
Absorption: In absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.
What is the amplitude on a wave?
Amplitude is a measurement of the amount of energy transferred by a wave. Amplitude on a transverse wave is typically measured as the distance between the peak or trough of the wave and the equilibrium position, or the position of the medium at rest.
What wave causes the medium to move parallel to the direction of the wave?
Does length affect the pendulum?
Yes! The longer it is the slower it goes!
What is the wave with the smallest wavelength?
Gamma rays!
What does it mean when light is transparent vs translucent vs opaque?
Transparent means all of the light passes through
Translucent means some of the light passes through which makes it less clear
Opaque means no light passes through so you can't see it
In the equation t=2pie square root l/g what do the T, L, and G represent?
T represents the time it takes for the pendulum, L represents the length of the pendulum, and G represents how much gravity the pendulum has.
Does the wavelength affect how much energy a wave has?
Yes! A wave with a smaller wavelength will have less energy and the other way around!
In between where the pendulum has only potential energy and where it only has kinetic energy what energy does it have?
Kinetic and potential energy!
List the types of waves in order from biggest wavelength to smallest wavelength!
Radio waves, microwaves, Infrared, visible light, ultraviolet, X-rays, gamma rays!
What wavelengths do red green and blue correspond to?
Red corresponds to longer wavelengths, green to medium wavelengths, and blue to shorter wavelengths.
In the equation t=2pie square root l/g amplitude and mass do not show up so do they affect the period of time on the pendulum?
They do not!
