Worked Solution & Example Answer:A student is standing 600 m from a firework display - Edexcel - GCSE Physics Combined Science - Question 2 - 2016 - Paper 1
Step 1
Describe how a student can measure the time it takes for the sound wave from the loud bang to travel 600 m.
Answer
To measure the time it takes for the sound wave to travel from the firework display to the student, the student can follow these steps:
-
Preparation: The student should stand at the specified distance of 600 m from the firework display.
-
Using a Stopwatch: The student needs to have access to a stopwatch for accurate timing.
-
Start Timing: Once the flash of light from the firework is observed, the student should start the stopwatch immediately.
-
Stop Timing: The student should listen for the loud bang that follows the visual cue and stop the stopwatch as soon as the bang is heard.
-
Calculate the Duration: The time recorded on the stopwatch will represent the time it takes for the sound wave to travel 600 m.
