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.

A sound wave strikes a wall and is reflected. What is the term for the reflected sound wave?
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.
Describe the difference between regular and diffuse reflection of waves.
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 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?
When a wave passes from a less dense medium to a more dense medium, which of the following occurs at the boundary? (1) The wave is completely reflected. (2) The wave is completely transmitted. (3) Part of the wave is reflected and part is transmitted. (4) The wave disappears.
Which of the following best describes the behavior of a wave at a free boundary? (1) The wave is reflected and inverted. (2) The wave is reflected without inversion. (3) The wave is absorbed. (4) The wave is amplified.
Which of the following best describes the transmission of sound waves from air into water? (1) All the sound is transmitted. (2) Some sound is reflected, and some is transmitted. (3) All the sound is reflected. (4) The sound stops at the boundary.
Which of the following is NOT a factor that affects the reflection of a wave at a boundary? (1) The angle of incidence (2) The frequency of the wave (3) The properties of the two media (4) The color of the wave
Fill in the blank: The _______ of a wave is the number of complete cycles per second.
Fill in the blank: The angle between the incident wave and the normal is called the angle of _______.
Fill in the blank: The ratio of the amplitude of the reflected wave to the incident wave is called the _______ coefficient.
Fill in the blank: The transmitted wave in a new medium has a different _______ compared to the incident wave, if the speed changes.
True or False: The amplitude of a reflected wave is always equal to the amplitude of the incident wave.
True or False: The direction of the reflected wave is always on the same side of the normal as the incident wave.
True or False: The frequency of a wave changes when it is reflected at a boundary.
True or False: The law of reflection applies to all types of waves, including sound, light, and water waves.
