Waves Flashcards
(26 cards)
What is a wave?
A disturbance that transfers energy from one place to another.
True or False: Waves can only travel through solids.
False
Fill in the blank: The distance between two consecutive crests in a wave is called the _____
wavelength
What is the formula for wave speed?
Wave speed = frequency × wavelength
What do we call the highest point of a wave?
Crest
What is the lowest point of a wave called?
Trough
Multiple Choice: Which of the following is a type of wave? A) Sound B) Light C) Water D) All of the above
D) All of the above
What is frequency measured in?
Hertz (Hz)
True or False: A wave can have both frequency and amplitude.
True
Fill in the blank: The time taken for one complete wave to pass a point is called the _____
period
What type of wave requires a medium to travel through?
Mechanical wave
What type of wave does not require a medium?
Electromagnetic wave
Multiple Choice: Which type of wave oscillates perpendicular to the direction of energy transfer? A) Longitudinal B) Transverse C) Both D) Neither
B) Transverse
What is the phenomenon called when waves bend around obstacles?
Diffraction
True or False: Constructive interference occurs when two waves combine to make a wave with a larger amplitude.
True
Fill in the blank: The principle that states that the total displacement of overlapping waves is the sum of their individual displacements is called the _____
superposition principle
What do we call the lowest frequency of a wave in a standing wave pattern?
Fundamental frequency
What is the term for the reflection of waves off a surface?
Reflection
Multiple Choice: Which phenomenon explains the change in wave direction when entering a different medium? A) Reflection B) Refraction C) Diffraction D) Interference
B) Refraction
What is the unit of measurement for amplitude?
It can vary depending on the wave type (e.g., meters for mechanical waves, volts for electromagnetic waves).
True or False: Sound waves are an example of transverse waves.
False
What type of interference occurs when two waves are out of phase?
Destructive interference
Fill in the blank: The phenomenon where waves combine to form a new wave pattern is known as _____
interference
What is the term for the speed of light in a vacuum?
Approximately 3.00 × 10^8 m/s
