D The mass has decreased. 3 Directions: Click on each answer you want to select. You must select all correct answers. Turning on an incandescent lamp is an example of energy transformation from electrical to chemical nuclear mechanical heat light radiant

2 4 Directions: Click and drag the text to the correct box. Label the diagram with the correct types of heat transfer. Conduction Convection Radiation 5 Timothy runs 51m in 14s. What is his speed? S = D/T A 714 m/s B 3.6 m/s C 0.28 m/s D 36 m/s 6 Which electromagnetic wave carries the most energy? A Gamma rays B Visible light C Ultraviolet rays D Radio waves

3 7 Drag and drop each choice into the correct box. Drag the choices from the left into the spaces on the right to rank the three materials from the best conductor to the worst. 8 Visible light has a wavelength the size of a A virus B bacteria C water molecule D protein

4 9 Directions: Type your answer in the box. 1 Which number represents a compression? 10 Directions: Fill in the blank Calculate the speed of a wave that has a wavelength is 2.0 meters and ia frequency is 2.0 Hz. Use the formula: speed = wavelength frequency m/s 11 Click and drag the term to the correct box. The diagrams below show three different wave behaviors. Click and drag the name of each wave behavior to the correct box below each diagram. reflection refraction diffraction

5 12 Click on a box to choose each statement you want to select. You must select all correct answers. Click on a box to choose the types of electromagnetic radiation that have frequencies higher than the light that we can see. You must select all correct examples. radiowaves microwaves ultraviolet radiation gamma rays X-rays 13 On a sunny morning, students standing in front of a store window noticed an image of themselves in the glass. Why did the students see their image in the glass? A Some of the light passed through the glass window. B Some of the light was absorbed by the glass surface. C Some of the light was reflected off the surface of the glass. D Some of the light separated into different colors.

6 14 A student is conducting an experiment with four different types of mirrors. Which mirror in the experiment converges light and produces an upright, magnified image of the candles? A Mirror 3 C Mirror 1 B Mirror 2 D Mirror 4 15 Type your answer in the box. Mr. Jones listens to the AM news station broadcasting at 780,000 Hz. What is the wavelength of this radio wave that is traveling at approximately 300,000,000 m/s? Use the equation wavelength = speed frequency to solve and round your answer to the nearest whole number. 385 meters

7 16 Directions: Click and drag the correct word to each box on the diagram. Label the parts of the wave diagram below: amplitude wavelength crest trough 17 As the frequency of a wave decreases, the wave's A period decreases B amplitude increases C speed decreases D wavelength increases 18 Echolocation is used as a means to locate objects by all the following creatures EXCEPT A birds B whales C dolphins D bats

8 19 Directions: Click on each answer you want to select. You must select all correct answers. Doctors perform ultrasound examinations to find abnormalities in the body. Which of these statements about ultrasound technology are true? Ultrasound machines use a combination of x- rays and sound to see inside the body. Ultrasound technology can be used to detect kidney stones without surgery. Only tumors above the skin can be detected by ultrasound machines. Doctors can see a three dimensional picture of internal structures with an ultrasound monitor. Ultrasound technology can only be used surgically. Ultrasound machines use sound waves to "see" organs. 20 If the amplitude (a) increased, what would happen to the sound made by this wave? A It would get softer. B It would have a higher pitch. C It would have a lower pitch. D It would get louder.

9 21 What do all three examples have in common? A The examples are producing a sound wave. B The examples are all producing the highest frequency possible. C The examples are producing a transverse wave. D The example are all producing the lowest wavelength possible. 22 The frequency of a wave is observed twice overtime. The frequency of this wave is A decreasing B staying the same C fluctuating D increasing 23 Directions: Click on each answer you want to select. You must select all correct answers. Which examples use resonance to amplify their initial sounds? Guitar Sonar Insect Conch Sea Shell Tuba

10 24 What numbers should be labeled rarefaction in the longitudinal wave? A 3 & 4 B 1 & 3 C 2 & 4 D 1 & 2 25 A disturbance that transfers energy from one place to another is called a A wave B motion C matter D force 26 The bat is using reflective sound waves to locate the butterfly. What is this application of sound called? A Echolocation B Sonogram C Sonar D Radar
