Waves Flashcards
What are the three primary colours of light
Red, Green, and Blue. They can be combined in different ways to make every other colour.
How does the wavelength affect the colour of light?
Longest - Red
- Orange
- Yellow
- Green
- Blue
- Indigo
Shortest - VioletThe splitting of white light into its different colours is called…
Dispersion
When blue light shines at a red object, the blue light is…
Absorbed
How does increasing the frequency affect a sound
It makes it a higher pitch
Angle of incidence equals angle of…
reflection
Speed =
Distance / Time
Define a longitudinal wave
The oscillations is parallel to the direction of travel
What is the speed of light in m/s
300 000 000 m/s
What is the speed of sound in m/s
343 m/s
if the angle of incidence = 45 degrees what is the angle of reflection
45 degrees
What colour would a magenta object appear in cyan light?
Blue
What does the pinna do
It collect sound waves
Define transverse waves
When the oscillation is perpendicular to the direction of travel
What does luminous mean?
It emits light
