0 1 This question is about a method to investigate interference by a diffraction grating
(required practical activity 2).
Light from a laser is shone onto the diffraction grating at normal incidence.
0 1 .1 State one safety precaution when using a laser in a school laboratory.
[1 mark]
A piece of squared paper is positioned parallel to the diffraction grating.
Figure 1 shows the pattern of four bright spots A, B, C and D that are seen on the
paper.
Figure 1
A student determines the distance x from the left-hand edge of the paper to the
centre of each spot.
Table 1 shows these data, including the uncertainty in each value of x.

Spot x / mm
A 60 ± 5
B 321 ± 5
C 553 ± 5
D 785 ± 5
