1. Waves can be transverse or longitudinal.
a. Describe how transverse and longitudinal waves are different.
[3 marks]
b. The diagram above shows two waves on one graph.
State one difference in quantity between the waves.
[1 mark]
c. State one quantity that is the same for both waves.
[1 mark]
d. Is the wave transverse or longitudinal?
[1 mark]
e. Every second, 6 waves pass through the gap in the barrier in this ripple tank.
If the waves have a wavelength of 0.014 metres, what is the speed of the water waves in the tank?
Show your calculations.

2.
a. The diagram below shows the position of an object and image of the object. Use the diagram to answer the questions:
i. What do the points labelled F represent?
[1 mark]
ii. What type of lens is shown in the diagram?
[1 mark]
iii. How can you tell from the diagram that the image is real and can be put on a screen?
[1 mark]
iv. Explain the difference between a virtual image and a real image.

3. Students are investigating waves and used a ripple tank as shown below.
a. Show how the wave acts as it moves into the deep region – show its refraction from shallow to deep, on the diagram above.
[1 mark]
b. Explain how the waves act as they move towards the deeper region.
[2 marks]
c. The students decide to measure the waves at a point where the water is the same depth.
The results were as follows:
Wavelength: 0.35m
Period of each wave: 0.46s
Calculate the speed of the wave correct to 3 significant figures and use the correct unit.
Speed: Unit:
Plunger
Shallow region Wave front
Deep region
4. Ultraviolet and infrared rays have different frequencies and can be harmful to humans.
a. Describe how ultraviolet and infrared rays can be harmful because of their wavelengths.
[6 marks]
5. The different waves on the Electromagnetic spectrum are shown below.
a. What is the arrow showing?
Place a in the correct box:
[1 mark]
b. The range of wavelengths in the Electromagnetic spectrum is?
Place a in the correct box.
[1 mark]
6
A. decreasing wavelength, increasing frequency B. increasing wavelength, decreasing frequency C. decreasing wavelength, decreasing frequency D. increasing wavelength, increasing frequency
A. 10-15 to 104 B. 10-5 to 106 C. 10-6 to 108
Radio waves Microwaves Infared Visible light Ultraviolet X-rays Gamma rays
c. Radio waves have a speed of 3.0 x 108 m/s and a wavelength of 1500m. What is the frequency of the radio wave? Show your calculations and give the correct unit.

d. The table below shows the hearing ranges of different animals:
i. Which mammal has the largest range of hearing?
[1 mark]
ii. State a frequency that an elephant can hear but a tiger cannot. Include the unit.
[1 mark]
Animal Range of hearing in Hz
Elephant 5 Hz – 10 kHz
Human 20 Hz – 20 kHz
Dog 20 Hz – 30 kHz
Bat 20 Hz – 160 kHz
Tiger 30 Hz – 50 kHz
Dolphin 40 Hz – 110 kHz
e.
i. What is ultrasound?
[1 mark]
ii. How can ultrasound be used in medicine?
[1 mark]
iii. Ultrasound can also be used in exploration. The diagram below shows how it can be used to measure the depth of water below a ship.
If the pulse sent out from the ship takes 0.90 seconds for the emitted ultrasound to be received back at the ship, calculate the depth of the water (assuming the speed of ultrasound to be 1600m/s).

6. A boy is walking on a river bank and spots a fish in the water. The diagram shows where he thinks the fish is in the water.
a. On the diagram, draw an X where the fish actually is.
[2 marks]
b. Why does the fish appear to be in a different place to where it actually is?
