1 FORMATIVE MINI ASSESSMENTS Third Grading Period March STUDENT NAME DATE PERIOD Science Physics Read each question and choose the best answer. Be sure to mark all of your answers. 1 The diagram below shows two waves, A and B. 3 The speed of sound depends on the A amplitude of the wave B Doppler Effect C properties of the medium it s traveling through D source of the sound Which conclusion can be drawn about the two waves? A Both waves are transverse waves. B Both waves are longitudinal waves. C Wave A is a longitudinal wave, and Wave B is a transverse wave. D Wave A is a transverse wave, and Wave B is a longitudinal wave. 4 A teacher bounces a ball off the wall, then shines a laser off of a mirror. This teacher is demonstrating F polarization G reflection H refraction J interference 2 Which example below is a type of longitudinal wave? F Radio wave G Light wave H Ocean wave J Sound wave 5 One tuning fork is struck and placed next to an identical tuning fork. The two tuning forks do not touch. The second tuning fork starts to vibrate because of A interference B the Doppler Effect C resonance D standing waves SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 1

2 Use the graph below to answer questions 6 and 7. The graph below shows how an anchored boat rises and falls with the waves on a lake. distance (cm) time (s) 6 What is the period of the boat s motion? F 0.1 Hz G 3 cm H 1.2 cm/s J 10 s 7 What is the amplitude of the boat s motion? A 0.1 Hz B 3 cm C 1.2 cm/s D 10 s SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 2

3 8 Which label on the model represents wavelength? F Q G R H S J T 9 Four different electromagnetic waves are shown in the figure above. When comparing these four waves, all of the following statements are true except A wave I has the longest wavelength B wave IV has the highest frequency C wave II has a higher frequency than wave I D wave IV has a longer wavelength than wave III SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 3

4 Volume Chart Decibels Examples 0 threshold of hearing 10 ordinary breathing whispers ordinary household sounds activities such as turning newspaper pages automobile engines and vacuum cleaners noisy stores ordinary conversation heavy street traffic trains and subways air drills and riveters thunderclaps and jet engines 120 threshold of pain 10 Sounds that measure over 90 decibels for a prolonged period of time have been shown to damage the human ear. Which of the following workers should wear hearing protection? F Traffic policeman G Department store clerk H Church daycare worker J Jet aircraft mechanic SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 4

5 11 One thing that bothers fishermen is the fact that sunlight reflecting off the water prevents them from seeing any fish that are near the surface of the water. However, polarized sunglasses block the annoying reflection of light. Polarized lenses reduce reflections by A reflecting the light waves back to the water at the same angle they were received B allowing only light waves vibrating in a single plane to pass through the lens C being tinted the same color as the sky D having a low index of light refraction 14 A student needs eye glasses or contact lenses to see objects clearly when he reads. The reason the student can see better with eye glasses is because when light waves travel through curve glass, the light rays are F reflected G dispersed H refracted J transformed 12 A recent study concluded that hearing aids are an effective treatment for hearing loss. People with different types of hearing loss were included in the study. Which question would help in determining whether the conclusion above is valid? F What was the average age of the people in the study? G What was the most common occupation of the people in the study? H How many people were included in the study? J How many people in the study had vision problems? 15 Which of the following describes a disadvantage of using solar cells as an energy source? A Solar cells generate large quantities of waste. B Solar cells can be used to charge batteries. C Solar cells release gaseous by-products. D Solar cells are dependent on available sunlight. 13 A train is approaching a railroad street crossing, and sounds its whistle to warn approaching drivers. As the train passed the crossing with its whistle still blowing, the pitch (frequency) of the sound changes from high to low. This is an example of A refraction B the Doppler Effect C reflection D interference TEA In this circuit, how much current flows through the light bulb? F 0.5 amps G 1.50 amps H 3.0 amps J 4.5 amps SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 5

6 17 A student used 6 wires, three lights and a battery to form a parallel circuit as shown above. Which wire, when removed, will cause two of the three lights to go out? A Wire 1 B Wire 3 C Wire 5 D Wire 6 18 The electric circuit shown above can best be described as a F series circuit G closed circuit H short circuit J parallel circuit 19 If the lights in your house were connected in series circuits instead of parallel circuits, whenever you connected another light the other lights that were already on would A all go out completely B all get brighter C all get dimmer D not be affected SAISD, Edusoft, TEA, NY Regents Physics FMA March 11 Page 6
