light and colour 1
The angle of incidence equals the angle of reflection
What is the law of reflection?
It is 299,792,458 meters per second
What is the speed of light?
This is the angle between the incident ray and the normal
What is the angle of incidence?
A result which does not fit the pattern of the other results obtained
What is an anomalous result?
The ray travelling towards the mirror
What is the incident ray?
This shows the light travelling back from the mirror
What is reflected ray?
It happens when light bounces off a smooth surface
What is reflection?
When light is reflected from particles and uneven surfaces
What is scattering?
It is the line drawn at 90o to the mirror at the point where rays hit the mirror
What is the normal?
A straight or curved line drawn through the middle of a set of points to show the pattern of data points
What is a line of best fit?
Green or red or blue
What is a primary colour?
It is a form of energy that travels in straight lines
What is light?
The bending of light when it enters a different medium
What is refraction?
The angle between the reflected ray and the normal
What is angle of reflection?
A flat mirror
What is a plane mirror?
A straight line which shows the direction of light
What is a light ray?
A reflection of an object
What is an image?
It is used to measure angles accurately.
What is a protractor?
The angle between the refracted ray and the normal
What is angle of refraction?
How deep something appears to be
What is apparent depth?
How deep something really is
What is real depth?
The splitting of white light into a spectrum of colours
What is dispersion?
The incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.
What is the second law of reflection?
Transparent object that refracts light
What is a prism?
The way in which an object takes in the energy reaching its surface
What is absorption?
