PAG 6.2 - Experiments with Light Flashcards
1
Q
Refraction
A
Changing of speed of a wave as it passes into a new medium of different optical density
2
Q
What quantity does not change during refraction?
A
frequency remains constant
3
Q
Suggest a suitable source to investigate refraction through a glass block
A
Ray box, lower risk than laser
4
Q
What is the risk of using a laser to investigate refraction through a glass-block
A
May reflect some of the light and this could enter your eye and cause damage
5
Q
How can you measure the angle of refraction in this experiment?
A
Draw around glass block
Mark where ray enters and leaves block and remove block
Connect lines and measure angle
