Wave Speed
Physics ⇒ Waves and Sound
Wave Speed starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Wave Speed.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
Describe how temperature affects the speed of sound in air.
Describe what happens to the speed of a wave if the medium changes from air to water.
Describe what happens to the wavelength of a wave if its speed increases but the frequency stays the same.
Explain why electromagnetic waves can travel through a vacuum but sound waves cannot.
Explain why sound travels faster in solids than in gases.
A seismic wave travels through the Earth at 6,000 m/s. If the frequency of the wave is 2 Hz, what is its wavelength?
A sound wave travels through two different materials: Material A and Material B. In Material A, the speed is 400 m/s, and in Material B, it is 200 m/s. If the frequency of the sound is 1000 Hz, what is the difference in wavelength between the two materials?
A wave travels along a rope and covers a distance of 45 meters in 9 seconds. What is the speed of the wave?
The speed of sound in air is approximately (1) 340 m/s (2) 1500 m/s (3) 300,000,000 m/s (4) 3 m/s. Choose the correct answer.
Which of the following best describes the relationship between wave speed, frequency, and wavelength? (1) Wave speed = frequency × wavelength (2) Wave speed = frequency ÷ wavelength (3) Wave speed = wavelength ÷ frequency (4) Wave speed = frequency + wavelength
Which of the following is NOT a factor that affects wave speed? (1) Medium (2) Frequency (3) Temperature (4) Density of medium
Which of the following is the correct SI unit for frequency? (1) Hertz (2) Meter (3) Second (4) Newton

Fill in the blank: The speed of a wave is measured in __________ per second.
True or False: All electromagnetic waves travel at the same speed in a vacuum.
True or False: Increasing the frequency of a wave will always increase its speed.
True or False: The speed of a wave can be calculated if you know its frequency and wavelength.
True or False: The speed of a wave depends on the medium through which it travels.
