The two key components of an electromagnetic wave.
Electric and magnetic field
Red, orange, yellow, green, blue, indigo, violet
When light shines on a translucent surface it.....
Scatters light.
The name of light that is bent.
Refraction.
The transparent covering over the eye.
Cornea
An example of a transverse wave.
Electromagnetic wave.
Red
Absorb or reflect the light.
How is the angle of incidence in reflected light related to the angle of reflection?
It is the same angle.
The part of the eye that light needs to reflect onto before it sends a message to the brain.
Retina.
The only type of electromagnetic wave that people can see.
Visible light
The colour(s) absorbed when light hits a blue object.
All colours except blue.
Seeing a straw in a glass of water is an example of...
Refraction.
The index of refraction in this medium is higher than the index of refraction of air. (several answers here)
Water, glass, diamond...
The white covering of the eye that helps the eye to keep its shape.
Sclera
When light is filtered so that only waves that vibrate in one direction pass through.
Polarized light.
The primary colours of light.
Red, blue and green.
A concave lens will make the light rays......
Light travels the fastest in this medium.
Air
The part of the eye that gives it the colour
Iris
What part of they eye send signals to the brain?
The Optic nerve
The part of the eye that can change shape to bend light towards the retina.
