Wave Reflection and Transmission

Physics ⇒ Waves and Sound

Wave Reflection and Transmission 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 Reflection and Transmission. 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 9
A light wave strikes a mirror at an angle of 45° to the normal. At what angle will it be reflected?
A sound wave hits a boundary and some of its energy is absorbed, some is reflected, and some is transmitted. What is this process called?
A sound wave is incident on a boundary at 60° to the normal. What is the angle of reflection?
A sound wave travels from air (speed = 340 m/s) into water (speed = 1500 m/s). If the frequency is 500 Hz, what is the wavelength in water?
A wave is incident at 30° to the normal on a flat surface. What is the angle of reflection?
A wave pulse travels down a rope and reflects off a fixed end. What happens to the pulse?
A wave pulse travels down a rope and reflects off a free end. What happens to the pulse?
A wave pulse travels from a light string to a heavy string. What happens to the reflected pulse?
A wave travels from air into water. What happens to part of the wave at the boundary?
Describe what happens to a wave when it is transmitted into a medium with a lower speed.
Describe what happens to the amplitude of a wave when some energy is absorbed at a boundary.
Describe what happens to the direction of a wave when it is reflected from a smooth surface.
Explain what happens to the wavelength of a wave as it passes from a less dense to a more dense medium.
Explain why a rough surface scatters reflected waves in many directions.
Explain why a wave is partially reflected and partially transmitted at a boundary between two media.
Explain why echoes are not usually heard in small rooms.
If a sound wave moves from air into water, does its frequency change?
If a wave is transmitted into a medium where it travels faster, what happens to its wavelength?
State the law of reflection.
What is an echo?
