Objective 5 The student will demonstrate an understanding of motion, forces and energy
5. Science ConceptIntegrated Physics and Chemistry • The student knows the effect of waves in everyday life. The student is expected to A) Demonstrate wave types and their characteristics through a variety of activities such as modeling with ropes and coils, activating tuning forks and interpreting data on seismic waves B) Demonstrate wave interactions including interferences, polarization, reflection, refraction and resonance within various materials
5A IPC B 10-04 Side to side movement rolling movement Back and forth movement rolling movement Which illustration best demonstrates compression waves?
5B IPC C One tuning fork is struck and placed next to an identical fork. The two forks do not touch. The second tuning fork starts to vibrate because of --- • interference • the Doppler effect • resonance • standing waves
5A IPC A 10/06 Which label on the model represents a wavelength? • Q • R • S • T
5B IPC C 11/06 An empty cup was tightly covered with plastic wrap, and a few grains of salt were sprinkled on top of the plastic. When a tuning fork was struck and placed slightly above the plastic wrap, the salt began to move. Which characteristic of waves does the movement of the salt best demonstrate? • Echo formation • Diffraction • Resonance • Specular reflection
5B IPC D 11/06 Laser Light Striking a DVD When a DVD is read, laser light touches the DVD surface and is then measured at location A. What allows light to return to location A after striking the DVD surface? bounce back • Conduction • Refraction • Magnification • Reflection
5B IPC A 11/04 The pitch of a sound made by plucking a guitar string is determined by the --- • frequency of the vibration produced • strength of the plucking force • distance between the strings • shape of the guitar body
5B IPC A 11/05 A tuning fork with a frequency of 256 Hz vibrates when struck. Because of these vibrations, a nearby tuning fork begins to vibrate without being struck. Which of the following best accounts for the vibrations of the second tuning fork? • Resonance • Polarization • Diffraction • Refraction
5B IPC B 11/06 A guitar player is seated next to a piano. The piano player strikes an E key on the piano. The guitarist reports that this causes the E string on his guitar to vibrate. What is the name of this phenomenon? • Polarization • Resonance • Reflection • Diffraction
5B IPC B 11/04 When trying to spear a fish in water, a person needs to take into account the way light bends as it moves from water into the air. The bending of light as it passes from one medium into another is known as --- • Reflection • Refraction • Diffraction • Polarization
5B IPC F 11/05 A surface wave generated by an earthquake was recorded at Seismic Station 1. Forty seconds later the same wave was recorded at Seismic Station 2. What accounts for the time difference? • The origin of the wave is closer to Seismic Station 1. • The speed of the wave decreases with distance. • The wavelength is longer at Seismic Station 2. • The wave frequency increases when the wave passes through soil. no no no
5B IPC D 11/04 2 x 8 1 x 2 = 16 = 2 2 x 8 3 x 3 = 16 = 9 Which wave has the greatest velocity?
5B IPC D 11/04 2 x 8 1 x 2 = 16 = 2 2 x 8 3 x 3 = 16 = 9 Which wave has the least velocity?
