1.1. State what is meant by polarisation.

1.2. Table 1

Complete the missing information in the columns in Table 1 to show which of the waves listed are transverse or longitudinal and whether they can be polarised .

1.3. Figure 1 shows unpolarised light directed towards a polarising filter A.

Figure 1

Polarising filter B is placed directly after A and is identical except rotated by 90º. 

State and explain what happens to the light after it is incident on polarising filter B.

1.4. Instead of unpolarised light, light polarised at an angle θ is incident on a vertically polarising filter A. 

Katie says that the light will become completely vertically polarised with no loss in intensity after polarising filter A. Jon says that the light will be vertically polarised with a reduced intensity after polarising filter A. 

State who is correct and clearly explain your answer.
