Types of waves
Name one type of Electromagnetic wave.
Any of the following examples: Light, Microwaves. Infared, X-rays, Ultraviolet, Radio waves, Gamma.
Where is the crest on a wave?
On the highest point of the wave.
What is refraction?
Bending of a wave as it changes speed in a new medium.
What colors are a part of color addition?
Red, Green, Blue.
Metre
What are the two types of mechanical waves?
Longitudinal and transversal
Where is the wavelength on a wave.
The distance between two consecutive points. An example being crest to crest or trough to trough.
What is reflection?
When incident light hits an object and bounces off.
What colors are a part of color subtraction?
Cyan, Magenta, Yellow
What is the frequency of a wave mean?
The number of waves that pass a fixed point in a given amount of time.
What are the two types of waves?
Electromagnetic and mechanical
Where is the trough of a wave?
The lowest point of a wave.
What is diffraction?
Then bending and spreading of waves around an obstacle.
Where do we see color addition in our real life? When do we see color subtraction?
Color addition: Phone screen
Color Subtraction: Paint
What does sound resonance mean?
Sound resonance is when the frequency of an initial object's vibration matches the resonant frequency.
What kind of wave is a sound wave?
Longitudinal
Where is the amplitude of a wave?
Amplitude is the vertical distance between the midline and one of the extremum points.
What happens to wavelength if frequency increases?
Wavelength decreases when frequency increases.
The production of various colors of light by mixing of the three primary colors of light.
What happens if you play a frequency at the natural frequency to a perfectly made glass.
The glass is going to break.
What kind of wave is an ocean wave?
Transversal.
Go to the white board, draw a wave, and label the following things correctly.
Crest, trough, wavelength, amplitude.
Will be decided in person.
What happens to frequency if a wavelength increases?
Decreases.
What is color subtraction?
Wavelengths of illuminating light source are absorbed by pigments in an object.
In music, frequency is called...?
Pitch.
