we can produce a narrow ray of light using a __ box, lens and a slit
ray box
1 of 13
why should ray boxes be switched off when not being used? (risk)
they get hot
2 of 13
first draw line down center of paper. then use protractor to draw a line at __ degrees. label this N as it's the normal
90 - right angle
3 of 13
place __ block (material?) against line so normal is perpendicular to it
glass
4 of 13
draw around glass block. turn off light. direct ray box so it hits... (which line?) this will be the incidence ray
the normal
5 of 13
the angle of incidence is the one between the normal and the ....
incidence ray
6 of 13
adjust ray box to change angle to incidence. at certain angle the ray will ___ from surface of block
reflect
7 of 13
we can also see ray leaving block my other side. this is the ___ ray
transmitted
8 of 13
mark all three rays with crosses. turn lights on and ray box off. draw straight line from where crosses are to mark the rays. we then draw a line from normal to....
transmitted ray to show where it traveled
9 of 13
measure the angles of....
angle of incidence, reflection, refraction (all from normal to ray)
10 of 13
repeat experiment with new ___ (what's changed?)
material
11 of 13
the angles of incidence and reflection should... (stay same/change?)
stay same - don't depend on material
12 of 13
refraction angles ___ (stays same/changes?)
changes - is different for different materials
