1

Draw the refraction of light in glass

2

What is the image produced by a conveging lens like when the object is more than two focal lengths from the centre of the lens? and Draw it 

  • The image is real 
  • The image is inverted 
  • The image is diminished (smaller than the object)
  • Examples: the eye and cameras 

3

What is the image produced by a conveging lens like when the object is between one and two focal lengths from the centre of the lens?

  • The image is real 
  • The image is inverted (upside down)
  • The image is magnified (larger than the object) 
  • Examples are the projector and the photocopier

4

What is the image produced by a conveging lens like when the object is two focal lengths from the lens 

  • The image is the same size as the object 
  • Image is real 
  • Image is inverted

5

What is the image produced by a conveging lens like when the object is between the principal focus and the centre of the lens?

  • The image is erect (the right way up)
  • The image is Virtual
  • The image is magnified 
  • The image is also on same side of the lens as the object 
  • Am example is a magnifying glass

6

Draw the reflection of wavefronts on a plane mirror 

7

Draw the diffraction of wavefronts at a glass block 

8

Diffraction of wavefronts at a gap

9

Diffraction of wavefronts at an edge 

10

Diffraction of wavefronts round an obstacle 

11

Draw the dispersion of white light through a prism (red and blue)?

12

How do gas particles exert a high pressure on the walls on the inside of a container?

  • molecules hit walls 
  • Particles rebound and change momentum 
  • Exerts force on wall and there are many collisions across area of wall 

13

What is the difference between evaporation and boiling?

  • evaporation only occurs from the surface of the liquid. Boiling happens throughout the liquid 
  • Evaporations does not produce bubbles whereas boiling does 
  • Evaporation results in cooling whereas Boiling does not
