- 1. Multiple Choice
The water waves below are traveling along the surface of the ocean at a speed of 2.5 m/s and splashing periodically against Wilbert's perch. Each adjacent crest is 5 meters apart. The crests splash Wilbert's feet upon reaching his perch. How much time passes between each successive drenching?2 seconds.5 seconds1.5 seconds12.5 seconds - 2. Multiple ChoiceA teacher attaches a slinky to the wall and begins introducing pulses with different amplitudes. Which of the two pulses (A or B) below will travel from the hand to the wall in the least amount of time?they arrive at the same timeABthe waves won't transmit through a slinky
- 3. Multiple ChoiceThe teacher then begins introducing pulses with a different wavelength. Which of the two pulses (C or D) will travel from the hand to the wall in the least amount of time ?CDits a tieno waves travel through slinkys
- 4. Multiple ChoiceThe time required for the sound waves (v = 340 m/s) to travel from the tuning fork to point A is ____ .17 seconds.059 seconds1.7 seconds6800 seconds
- 5. Multiple ChoiceA pendulum is observed to complete 23 full cycles in 58 seconds. Determine the period and the frequency of the pendulum..40 Hz and 2.5 seconds1334 HZ and 25 secondsCan not callculate without the lengthCan not calculate without the vibrations
- 6. Multiple ChoiceTwo waves are traveling through the same container of nitrogen gas. Wave A has a wavelength of 1.5 m. Wave B has a wavelength of 4.5 m. The speed of wave B must be ________ the speed of wave A.A is three times a s fast as B1/3the same asB is 3x as fast
- 7. Multiple ChoiceWhile hiking through a canyon, Noah Formula lets out a scream. An echo (reflection of the scream off a nearby canyon wall) is heard 0.82 seconds after the scream. The speed of the sound wave in air is 342 m/s. Calculate the distance from Noah to the nearby canyon wall.140 meters280 meters834 meters28 5278 meters
- 8. Multiple ChoiceTwo waves are traveling through the same container of nitrogen gas. Wave A has a wavelength of 1.5 m. Wave B has a wavelength of 4.5 m. The speed of wave B must be ________ the speed of wave A.A is three times a s fast as B1/3the same asB is 3x as fast
- 9. Multiple ChoiceAn automatic focus camera is able to focus on objects by use of an ultrasonic sound wave. The camera sends out sound waves that reflect off distant objects and return to the camera. A sensor detects the time it takes for the waves to return and then determines the distance an object is from the camera. The camera lens then focuses at that distance. If a sound wave (speed = 340 m/s) returns to the camera 0.150 seconds after leaving the camera, then how far away is the object?25.5 meters51 meters2266 meters1/51 meters
