Which is a property of light waves but not sound waves?
why cannot it be both? by definition, amplititude is the extreme range of fluctuating quantity. swing range of a pendulum, current flow,bla,bla,bla. amplitude MODULATION is in reference to radio waves with regards to signal RANGE ie: AM Radio- amplitude modulation am bounces and the range of frequency is modulated within the extreme band withs of the wave.
The measure of a waves intensity?
The measure of the intensity of a wave is referred to as its amplitude.
What occurs when two or more waves overlap and combine?
They superpose. Energy of the waves are redistributed to form a resultant wave with amplitude given by the summation of individual wave's amplitude. If the two waves are of same frequency, speed and amplitude and travelling in opposite direction den stationary waves are form.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
What transfers vibrations to the inner ear?
No. Vibrations are changed into signals by the "hairs" (a part of nerve cells, not real hair) in the inner ear. The function of the bones of the middle ear is to change the low pressure, high amplitude sound waves into high pressure, low amplitude waves - for the inner ear to process.
A light waves brightness depends on the?
amplitude of the light wave!
What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
what is amplitude?
Amplitude refers to the amount by which something is displaced from the middle of its periodic motion. It can mean the maximum disturbance from the neutral position of a wave. It represents the intensity of a vibration, e.g. the loudness of a sound.
A change in loudness results from a changing of the of the sound waves.?
A change in the amplitude.
What are two main categories for waves?
wavelength, amplitude or maybe you meant sound and light (waves?)
Is the color of light determied by the speed of the light waves?
the color of light is determined by the ____ of the light waves A. medium B.speed C.frequency D. amplitude
What happens when you change the amplitude?
Simple Case:For simple waves, changing the amplitude does not change any other basic wave characteristic, e.g. frequency, wavelength.Amplitude is usually associated with the quantification of how much stuff is waving or how strongly it is waving, e.g. water waves and sound waves. It nearly always then is a measure of the energy of a wave which is usually proportional to the square of the amplitude. For sound and similar waves we say a change of amplitude changes the intensity of the wave.More complex Cases:The basic characteristics of a simple harmonic wave are the amplitude, frequency and wavelength., There are further longitudinal and transverse waves, so the direction of associated with the movement of whatever is oscillating is another characteristic.The amplitude of a wave is the measure of the maximum magnitude of whatever is oscillation. For simple harmonic waves, there is a sinusoidally varying quantity which is the amplitude. When the amplitude changes, it is just that magnitude changing or such simple waves. As stated above, this is usually associated with a change of energy or intensity.For some waves, particularly those which are not simple harmonic waves, change in amplitude can cause other effects. These are called nonlinear effects.A few examples are known from daily life. A ripple on the surface of water does not have the same properties as a giant ocean wave. In the case of water, amplitude does alter wavelength and frequency. The character of a wave changes. The electrical waves traveling through the electrical circuit of an amplifier for a loudspeaker system have properties that are not simply proportional to amplitude of the signal can can produce those loud screeching noises and distortions. People who wear glasses which darken in bright sunlight are experiencing a nonlinear effect. Even the oscillation of a pendulum is nonlinear with the period of the pendulum changing as the amplitude increases.
What happens if 2 light waves with the same amplitude interfere?
Their amplitude is not the important variable - their frequency is . If two light waves of the same frequency interact, then an interference pattern will be seen. This is the basis of the 'double slit' experiment designed to demonstrate that light may be considered to indeed be waves.
What type of waves have amplitude?
All waves have amplitude.
Wavelength frequency amplitude and what are the four characteristics of waves that can change?
wavelengh, frequency,amplitude, and wave speed
If the amplitude of the waves coming from a light bulb decreased what will you expect to happen?
I would expect the light bulb to fail.
How can you change the amplitude of the wave?
By increasing the frequency and decreasing the wavelength for more energy.
