Which frequency of light travels the fastest?
Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).
What is it called when two or more waves overlap and combine to form a new wave?
interference. when two or more waves overlap and combine to form a new wave. standing wave. special type of wave pattern that forms when waves equal in wavelength and amplitude, but traveling in opposited directions, continuously interfere with each other. resonance.
What happens when two waves come together?
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.
What is it called when two waves combine?
Interference is what happens when two or more waves come together. Depending on how the peaks and troughs of the waves are matched up, the waves might add together or they can partially or even completely cancel each other.
What happens when two light beams collide?
The two light beams can create particle-antiparticle pairs, with the same total energy and the same total momentum and angular momentum as two photons, one from each beam, would have. Other processes involving more photons can also occur but even more rarely.
What are the 4 properties of wave?
However, all waves have common properties—amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave’s length, and frequency describes how often it occurs. Speed describes how quickly a wave moves.
What are period waves?
The wave period is the time it takes to complete one cycle. The standard unit of a wave period is in seconds, and it is inversely proportional to the frequency of a wave, which is the number of cycles of waves that occur in one second. The wave period is also dependent on the wavelength and the velocity.
What time period are sound waves?
f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation , it is measured in seconds. A sound wave has a time period of 0.0001 seconds.
