Flashcards on Waves: Properties and Phenomenon
Click on the flashcard to see the answer
What is a wave?
A wave is a disturbance that transfers energy from one place to another without transferring matter.
What are the two main types of waves?
The two main types of waves are transverse waves and longitudinal waves.
What are the properties of waves?
The properties of waves include amplitude, wavelength, frequency, and speed.
What is amplitude?
Amplitude is the maximum displacement of a point on a wave from its equilibrium position.
What is wavelength?
Wavelength is the distance between two consecutive points on a wave that are in phase.
What is frequency?
Frequency is the number of complete waves passing a point in a given time.
What is wave speed?
Wave speed is the distance traveled by a wave per unit time.
What is reflection?
Reflection is the bouncing back of a wave when it encounters a surface or boundary.
What is refraction?
Refraction is the bending of a wave when it enters a medium with a different speed.
What is diffraction?
Diffraction is the bending or spreading out of a wave as it passes through a narrow opening or around an obstacle.
What is interference?
Interference is the interaction between two or more waves that meet.
What is the law of reflection?
The law of reflection states that the angle of incidence is equal to the angle of reflection.
What is the law of refraction?
The law of refraction states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.
What is constructive interference?
Constructive interference occurs when two waves combine to form a wave with a larger amplitude.
What is destructive interference?
Destructive interference occurs when two waves combine to form a wave with a smaller amplitude.
