If the wavelength of light increases the frequency?
As the wavelength increases, frequency decreases. A wavelength is the distance from, say, a crest to a crest, or perhaps a trough to a trough. Frequency is essentially how many waves or how many cycles of a wave there are per unit of time, and we usually apply the term cycles per second or Hertz (which means cycles per second) to it.Wavelength is the physical distance the wave will travel as a single cycle of that wave occurs. And wavelength is a function of both frequency and of the speed of propagation of that wave. In any case, a longer wavelength is associated with a lower frequency. Increasing (lengthening) the wavelength decreases the frequency.
Does the speed of sound independent of frequency?
No, the speed of sound is not independent of frequency. In general, the speed of sound increases with increasing frequency. This relationship is due to the way sound waves travel through a medium, such as air or water.
How does sound affect frequency?
The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.
What happens when you increase the frequency of a sound wave?
Speed = distance / time [m /s]likewise:Speed of wave = wavelength x frequency [m /s]Since sound waves travel at a fixed speed through a medium* a drop in frequency must cause a corresponding increase in wavelength*Not always true. In water of example, lower frequency waves travel faster than higher frequency waves. When this happens the waves are said to be travelling through a dispersive medium.
Sound waves whose frequency is 300 Hz have a speed relative to sound waves in the same medium whose frequency is 600 Hz that is?
Since velocity of wave = frequency x wavelength (or v=fλ), and velocity is assumed to be the same for both since they're in the same medium,f1λ1 = f2λ2300λ1 = 9000λ2λ1/λ2 = 9000/300 = 30Thus, the wavelength of the 300Hz frequency sound wave is 30 times greater than the 9000Hz frequency sound wave.
Mcqs of waves motion and sound?
What is the definition of a wave in physics? A wave is a disturbance that transfers energy through a medium without transferring matter. What is the relationship between frequency and wavelength of a wave? Frequency and wavelength are inversely proportional - as frequency increases, wavelength decreases. How does sound travel through a medium? Sound travels through a medium by creating a series of compressions and rarefactions, which propagate as a wave through the medium.
How does the wavelength of waves travel with the same speed would change if the frequency of the waves increased?
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
If the wavelength of light increases the frequency?
As the wavelength increases, frequency decreases. A wavelength is the distance from, say, a crest to a crest, or perhaps a trough to a trough. Frequency is essentially how many waves or how many cycles of a wave there are per unit of time, and we usually apply the term cycles per second or Hertz (which means cycles per second) to it.Wavelength is the physical distance the wave will travel as a single cycle of that wave occurs. And wavelength is a function of both frequency and of the speed of propagation of that wave. In any case, a longer wavelength is associated with a lower frequency. Increasing (lengthening) the wavelength decreases the frequency.
Does speed increases as a wavelength increases?
No, speed is not directly related to wavelength in the context of light. In a vacuum, all wavelengths of light travel at the speed of light (approximately 299,792,458 meters per second). However, in a medium such as glass or water, different wavelengths of light travel at different speeds due to their interaction with the medium.
What affects the wavelength of a mechanical wave moving trough a medium?
The wavelength of a mechanical wave in a medium is affected by the speed of the wave in that medium and its frequency. As the speed increases, the wavelength decreases, and vice versa. Higher frequencies also result in shorter wavelengths.
When frequency increases what happens to diffraction?
When frequency increases, the diffraction of a wave becomes less pronounced. Higher frequencies have shorter wavelengths, making it easier for the wave to travel in a straight line and less likely to diffract around obstacles.
Does blue light have travel at a different frequency than red light in the same medium?
Yes. Blue light has a shorter wavelength, and therefore a higher frequency, than red light.
What is the relationship between frequency wave speed and wave length?
The speed of a wave is directly proportional to its frequency and wavelength. Higher frequency waves travel faster than lower frequency waves for a given medium. Additionally, waves with shorter wavelengths also tend to travel faster than waves with longer wavelengths.
Do waves with a shorter wavelengths travel faster than waves with longer wavelengths?
The physical length, short wavelengths are shorter than long wavelengthsThe frequency, short wavelengths are higher frequency than long wavelengthsThe energy per photon, short wavelengths have more energy per photon than long wavelengths
How is speed affected of the frequency or wavelength changes?
-- Changing the frequency/wavelength has no effect on the speed. (Notice that all electromagnetic waves, from wavelengths of perhaps 10-19 meters to perhaps 1,000 kilometers, travel with the same speed.) (Also notice that if the baritone sax plays a note together with the female vocalist, then you hear them at the same time, no matter how far from the stage you're seated.) -- Changing the frequency causes the wavelength to change, by the same factor in the opposite direction. -- Changing the speed causes the wavelength to change, by the same factor in the same direction.
Do higher frequency waves move faster?
The answer depends on the medium in which the wave is traveling. If the medium is non-dispersive, all frequencies will travel at the same speed (the group delay and phase delay will be the same). If the wave is traveling in a dispersive medium, the frequency of the wave will affect the speed (and the group delay and phase delay will not be the same). The type of dispersive medium also determines whether high frequency waves will travel faster or slower than lower frequency waves. A good example of light dispersion is demonstrated using a prism. In a prism, the higher frequencies travel at a different speed, and have a different refractive index than lower frequencies, this is how white light is split into its colored components using a prism.
Does the speed of sound independent of frequency?
No, the speed of sound is not independent of frequency. In general, the speed of sound increases with increasing frequency. This relationship is due to the way sound waves travel through a medium, such as air or water.
