Waves in General
What travels through matter and carries energy?
What are waves?
The highest part of a transverse wave
What is a crest?
What is a reflection and how can it be used to tell the color of an object
The bouncing back of a wave when it hits a surface through which it cannot pass. The color of the waves that are reflected hit the eye and are translated by the brain.
What is the ear?
What happens to wavelength if a wave frequency increases?
It gets shorter.
To receive signals or electrical messages.
The distance between crest to crest or trough to trough in a wave
What is a wavelength?
What size are visible wavelengths?
Between 380 and 780 nanometers.
What creates a sound wave in the air?
Vibration in the air particles makes a sound wave.
A wave pattern that has a lot of repetitions in a given amount of time has _______ frequency
What is high frequency.
The line running through the middle of the wave.
What is the midline?
The number of complete waves that pass a given point in a certain amount of time
What is frequency?
The amount of time it takes for a wave to complete one back and forth motion?
A wave period.
How loud or soft a sound is
What is pitch?
A short wave has a ______ amplitude.
What is low?
The material through which a wave travels.
What is a medium?
Describe the parts of an eye system when seeing objects.
The pupil lets light in, which bends and focuses the light into images you can see. They send these images to the retina, which sends the electrical messages about light to your brain to be decoded.
For a wave to appear, this must happen first.
A disturbance in a medium.
What causes sound waves to be louder than others?
High amplitude
An area that you cannot hear sound
Name 4 types of electromagnetic waves?
Possible answers: Radio waves, infrared waves, visible light waves, ultra violet waves, X-Rays, Gamma rays, microwaves
The distance between the resting point and crest
What is Amplitude?
Superposition
What type of wave is a sound wave?
Longitudinal waves - it moves in the same direction as the particles.
Light waves travel faster than ____ waves.
What is sound?
