TURNING FORCES: I understand that the forces can cause turning effects.
The causes are simple; you can have a turning effect of a force by the movement of a pivot, causing the lever to also move.
TURNING FORCES: I understand what is ment by the term moment.
Moment is the turning effect of a force.
TURNING FORCES: I know and can use the equation that links moment, force and distance.
Yes.
(moment=forcex distance)
(N=Nxm)
TURNING FORCES: I know the unit of moment.
Nm
REFLECTION: I can describe how light is reflected from a plane mirror.
Yes, the incident ray bounces of the normal creating a reflection.
REFLECTION: I can recall the law of reflection.
i=r
REFLECTION: I can draw ray diagrams to show reflection of light from a plane mirror.
CORRECT
REFRACTION: I can describe how light changes speed between air and either water of glass.
Yes, the ligh changes speed because of the density of each object.
REFRACTION: I can recall that a change in speed can make a light ray change direction.
Yes, since depending of the change, the light ray can bend away or towards the normal.
REFRACTION: I can recall which way light changes direction when it passes from air into glass or water.
When light passes through a less dense substance (air) to an more dense substance (glass or water) the light is bend towards the normal.
REFRACTION: I can recall which way light changes direction when it passes from glass or water into air.
When light passes though a dense substance (glass or water) into a less dense substance (air), the light is bend away the normal.
DISPERSION: I can recall that white light is made from different colours of light.
Yes, white light is made from 7 different colors.
Red has the smallest angle.
Violet has the biggest angle.
DISPERSION: I can describe how to use a prism to produce dispersion of white light.
Yes, by the refraction the colors disperse.
DISPERSION: I can list the seven colours in order, starting from red.
ROY G BIV
Red, Orange, Yellow, Green, Blue, indigo and Violet.
COLOURS: I can recall the three primary colours of light.
Blue
Red
Green
COLOURS: I can recall the colours that are made when these primary colours are added together.
Cyan, Magenta, Yellow and White.
COLOURS: I understand that filters work by subtracting light.
Yes…
A little bit.
When putting on a filter on light of a certain color, only that color while pass through and the others get absorbed (substracted).
COLOURS: I can predict what will happen when light of different colours shines on filters of different colours.
For what I understand, the primary colors OBJECTS will look black when put on other color light (not only primary color of light).
COLOURS: I understand why coloured objects appear coloured whenseen in white light.
White ligt is composed of the colors of that object, so the object then will let get through the color the object is composed and absorbed others. (substract others).
COLOURS: I can predict the colours that objects will appear to be, when seen in light of different colours.
Yes,
I think.
TURNING FORCES QUESTION I GOT WRONG: In wich direction does a moment act?
Perpendicular to the applied force.
REFRACTION QUESTION I GOT WRONG: Between which two substances would there be MOST refraction
Air and Diamond
