# Phenomena of Wave - Reflection and Refraction

The SPM Physics Workbook is developed under the One-School.net Free Books Project. The content of this book is strictly follow Malaysia SPM (Sijil Pelajaran Malaysia) syllabus. The aim of this project is to provide a complete electronic supplementary network for students to develop self-learning skills by breaking the spoon-feed rituals and to encourage them to compile educational information from the Internet.
1. Which of the following physical quantities of a wave will change after reflection?

frequency
direction
speed
wavelength

2. Which of the following is not the application of reflection of wave?

Mirror
Sonar
Magnifying glass
Fiber optic

3. Which of the following properties of the water wave will change when the wave propagate from region A to region B?

I     Speed
II    Wavelength
III  Frequency
IV  Amplitude

I and II
III and IV
I and III
II and III

4. When waves moving towards the beach, the shape of the wavefronts will take on the contours of the beach as the waves get closer to it. This phenomenon is due to

refraction of the wave.
diffraction of the wave.
interference of the wave.
reflection of the wave.

CalculationQuestion

5. Figure above shows a refraction of ripples in a ripple tank. If the speed of the ripples in region A is 0.1m/s, what is the speed of the ripples in region B?
0.20ms-1
0.05ms-1
0.01ms-1
0.02ms-1

6. A water wave moves from a shallow region to a deep region with a velocity of 25 cm s-1 and 30 cms-1 respectively. What is the ratio of the wavelength in the shallow region to the wavelength in the deep region?
2:1
1:2
6:5
5:6

7. A vibrator produces plane water waves that travel at a velocity of 20 cms-l. When the waves enter a shallower region, the wavelength becomes 1.6 cm and the speed of the wave become 16 cms-l. Determine the wavelength of the wave at the deeper region
3.0 cm
2.4 cm
5.0 cm
2.0 cm
