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 11
A sound wave strikes a wall and is reflected. What is the term for the reflected sound wave?
A sound wave travels from air (speed = 340 m/s) into water (speed = 1500 m/s). If the frequency is 1000 Hz, what is the wavelength in air?
A wave pulse is sent down a rope attached to a wall. The pulse is reflected. If the incident pulse is upward, what is the direction of the reflected pulse?
A wave pulse on a rope reaches a free end. What happens to the pulse upon reflection?
A wave traveling along a string encounters a fixed end. Describe what happens to the wave upon reflection.
A wave with a frequency of 500 Hz and a speed of 340 m/s travels from air into water, where its speed becomes 1500 m/s. What is its wavelength in water?
A wave with a speed of 200 m/s and a frequency of 50 Hz is incident on a boundary and enters a medium where its speed is 100 m/s. What is its new wavelength?
Describe the difference between regular and diffuse reflection of waves.
Describe what happens to the energy of a wave when it is partially reflected and partially transmitted at a boundary.
Explain why echoes are more likely to be heard in large empty halls than in small furnished rooms.
If a wave is incident at 30° to the normal, at what angle will it be reflected?
If the speed of a wave in medium 1 is 300 m/s and in medium 2 is 150 m/s, what happens to the wavelength as the wave passes from medium 1 to medium 2, assuming frequency remains constant?
What is the law of reflection for waves?
When a wave passes from a denser to a rarer medium, what happens to its speed?
