Ray Diagrams
According to the law of reflection, the angle of _________ and the angle of ___________ are equal.
According to the law of reflection, the angle of incident and the angle of reflection are equal.
___________ mirrors cave in towards the centre.
Concave mirrors cave in towards the centre.
Produces light through the production of heat.
What is incandescent?
An object will appear a colour because it...
absorbs and reflects selective wave lengths of light.
a property of an object that allows light to penetrate it, making it possible to see objects from the other side. (eg. window)
What is transparent?
The ___________ is the light ray that travels towards the reflective surface.
The incident ray is the light ray that travels towards the reflective surface.
__________ mirrors bulge out at the centre.
Convex mirrors bulge out at the centre.
Produces light through a chemical reaction that occurs in a living organism.
What is bioluminescence?
We use these lines to represent the direction of light.
a property of an object that allows light to pass through but scatters it in different directions.
What is translucent?
The ___________ is the line that is perpendicular to the reflecting surface.
The normal is the line that is perpendicular to the surface.
A _________ mirror forms images that are identical to objects.
A plane mirror forms images that are identical to objects.
The lights in the room are an example of this light souce.
What is florescence?
Light bounces off an object.
What is reflection?
a property of an object that will not allow any light to penetrate it.
What is opaque?
The reflected ray and the incident ray are on opposite sides of the _________.
The reflected ray and the incident ray are on opposite sides of the normal.
A line that is normal to the centre of a spherical mirror and passes through the centre of curvature is called the ___________.
A line that is normal to the centre of a spherical mirror and passes through the centre of curvature is called the principal axis.
Glow stick are a good example of this type of light source.
What is chemiluminescence?
the process in which light energy remains in the object it hits, and the light energy is converted to heat.
What is absorption?
All wave lengths are reflected back or mixing red, green and blue together.
How do you make white?
The image formed in a mirror is a __________ image.
The image formed in a mirror is a Virtual image.
The __________ is the distance between a focal point, and the mirror concave forms a ___________ image when the object is between the focal point in the mirror, cave mirrors form a __________ image when the object is between the centre of curvature and the focal point.
The focal length is the distance between a focal point, and the mirror concave forms a virtual image when the object is between the focal point in the mirror, cave mirrors form a real image when the object is between the centre of curvature and the focal point.
If an item glows in the dark it is said to be this type of light source.
What is phosphorescence?
the process in which light travels through an object and continues travelling.
What is transmission?
All wavelengths are absorbed or W - (C + M + Y)
How do you make black?
