[1 mark]

(b) Name types of light that is formed on spot P when any two of the lights from

torches K, L and M are switched on.

[1 mark]

(c) (i) Which torches that need to switch on if spot P appear cyan?

[1 mark]

(ii) What is the complementary colour for cyan?

SECTION C

1. Study the following statement

When a convex lens is used is to form image of an object, the imagedistance

varies with the object distance.

You are given a convex lens and a white screen.(a) Suggest a hypothesis to investigate the above statement.

(b) Describe an experiment to test your hypothesis in 11(a) based on thefollowing criteria.(i) Aim of experiment(ii) Identification of variables(iii) List of apparatus and materials(iv) Procedure or method(v) Tabulation of data

b) The colour that appears on the screen is the result of the subtraction of light by thecoloured filter and coloured screen.

Q 4.a) White

b) Secondary colourc)(i) K and L

(ii) Redd)(i) Black

(ii) Blue light is absorbed by the yellow card.

SECTION C

(a) When object distance increases, image distance decreases(b) (i) To investigate the relationship between object distance and image distance

of a convex lens

(ii) Manipulated variable - object distanceResponding variable - image distance

Fixed variable - focal length of the lens

(iii) Apparatus : a convex lens, a light bulb with power supply, a whitescreen, metre rule.

(iv) Procedure / Method

1. Put the object (bulb) at a certain distance ( must be more than F)

2. Adjust the screen position until a sharp image is formed on the

screen.3. Measure the object distance, u, and image distance, v.

4. Repeat step 1 to 3 using different values of u

(v) Assuming the focal length = 10 cm

u (cm) v (cm)15.0
