What effects intensity?
More important for what. If you use the analogy with sound, the frequency of light is the pitch of the sound (also the frequency of the sound waves), and the intensity is how loud it is. Both are equally important, but for different reasons. Sometimes you want a low frequency, sometimes you want a high frequency. Sometimes you want low intensity, others high intensity. Depends what you want it for.
Can you make a sound wave at a high enough frequency to convert it into light?
First of all, a sound wave is not a light wave. The frequency is not the only difference - it is quite a different type of wave. A wound wave might somehow INDUCE the creation of light waves (I don't know, it is just a possibility), but the sound wave ITSELF will not become a light wave. Second, the frequencies of light are extremely high; I am not sure whether sound can made at such frequencies.
How do you measure the frequency of the wave?
Since there are several kinds of waves, there are several ways to measure their frequency. Electrical waves can be measured with a frequency counter, an analog frequency meter or an oscilloscope. Ocean waves' frequency is measured with a stopwatch, but most people who measure ocean waves want to know how large they are rather than how fast they're coming.
Types of sound waves?
Sound waves are a longitudinal wave - a compression and rarefaction. These waves can vary in frequency, and by their complexity. Some sounds are pleasant and musical, whilst other waves are unpleasant or raucous. Sound waves also vary in amplitude. from the softest to the painfully loud.
What are the effects of music on fish?
They don't react because they can only feel minor vibrations and can't perceive it properly.
Factors that affect pitch and sound?
The amplitude of the sound wave, and how close the listener is to the source of the sound. The lower the amplitude, the lower the intensity. The further away a person in, the lower the perceived intensity.
How do you know about the inner layers of the earth?
Sound waves.
What are the two factors you need to determine the wave speed?
wave frequencys tell us the number of waves there are on that diagram.
How do you find velocity when only the frequency is given?
The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
How are radio waves used to find the speed of a moving object?
By using an phenomenon called the Doppler Effect, which causes waves (e.g. radio, light, sound) that are reflected off a moving object (or emitted by a source on a moving object) to shift frequency proportionally to the speed of the object.if the object is moving towards the observer the waves shift to a higher frequencyif the object is moving away from the observer the waves shift to a lower frequencyThe speed detector (e.g. RADAR gun) uses a method called heterodyning to "beat" the original transmitted radio waves with the received radio waves that reflected back from the object to generate a "difference frequency" that will be proportional to the relative speed of the object to the observer. This "difference frequency" is then fed to a frequency counter circuit and the result is scaled to be displayed in the correct units of speed that the user needs. For objects that emit the waves themselves (e.g. stars, galaxies) it is necessary to find spectral lines of known elements or compounds and measure how much the frequency of these spectral lines have shifted from their known standard frequency. If sound waves emitted by a vehicle (e.g. train whistle) you must somehow know the frequency of the sound source on the vehicle when it isn't moving (this may or may not be possible).
How do frequency wavelength and amplitude measure waves?
Amplitude defines how powerful waves are. Frequency and wavelength are measures of how often the wave fluctuates or far the wave is from crest to crest , These are related and can be calculated from each other if you know how fast the waves travel.
How can you tell with your eyes if two light waves have different frequencies?
We'd need a bit of information about the waves. If we knew the frequency, we'd know that the lower frequency wave had the greater (longer) wavelength. If we knew the period (the time for one cycle), we'd know that the one with the greater period would have the lower frequency and the greater (longer) wavelength. There might be some other things that would give us the answer, but we'd have to know what kind of wave we were dealing with. A mechanical wave like a wave on water or a sound wave? An electromagnetic wave? What was stated is true for all those waves.
