How do you find the wavelength of a sound emitted by a tuning fork at 440 vibrations-second?
The wavelength (λ) times the frequency (f) is equal to the velocity. The speed of sound in air is roughly 340 meters per second. That number obviously depends on the temperature of the air, the percentage of humidity, and many other things. If λf=v, then with some basic pre-pre-pre-algebra we can determine that λ=v/f. So, time to plug in numbers. λ = 340/440. λ = .7727 meters, or more precisely, 17/22
How many times per second does a tuning fork vibrate if it is producing a sound wave in helium gas with a frequency of 384Hz?
The frequency of a wave motion is the number of waves passing through a fixed position each second. Thus, the sound wave emitted from the tuning fork has a frequency of 384 Hz means that the fork is vibrating 384 times per second.
How do you find the wavelength of a sound emitted by a tuning fork at 440 vibrations-second and the speed of sound is 332 m per s?
Wavelength = speed /frequency = 332/440 = 75.45 cm(rounded)
What type of radiation is emitted when polonium 212 forms lead 208?
In this case alpha particles are emitted.
How is the peak frequency of emitted light related to the temperature of its incandescent source?
The peak frequency of emitted light is directly proportional to the temperature of the incandescent source, as described by Wien's displacement law. As the temperature of the source increases, the peak frequency of the emitted light shifts to higher values, resulting in a bluer appearance for higher temperatures and a redder appearance for lower temperatures.
Can you use the sound of an incoming car to measure its speed using the Doppler Effect?
Of course you can! Just like you can measure the velocity one is traveling based on the degree of time dilation. Here's the Doppler equation: F = (v + r)Fo / (v + s) where... F = frequency as OBSERVED Fo = frequency as EMITTED v = the velocity of sound (as it is in this instance) in a medium (for air, that's typically 331 meters per second + 0.6 mps PER DEGREE ABOVE 0 CELSIUS, if I remember correctly) R is the velocity of the person listening, and S is the velocity of the source. So, if you know the frequency of the sound the car is producing, the temperature of the air, the frequency you hear, and your own speed, you can deduce the velocity of the car approaching you.
What is a measure of the intensity of heat emitted by an object or substance?
Temperature is a measure of the intensity of heat emitted by an object or substance. It indicates how hot or cold an object is relative to a reference point. Temperature is typically measured in degrees Celsius or Fahrenheit.
How does the frequency of light emitted depend upon the temperature?
The black body equation describes this in detail, it is called Plank's law. All bodies emit electromagnetic radiation. The hotter the body the higher the average frequency. Refer to the links in the Related links for lots of detail.
How does the peak frequency of radiant energy relate to the absolute temperature of the radiating source?
The peak frequency of radiant energy is directly proportional to the absolute temperature of the radiating source, as described by Wien's displacement law. As the temperature of the source increases, the peak frequency of the emitted radiation also increases. This means that hotter objects emit higher frequency (shorter wavelength) radiation.
Temperature of the sun's photosphere?
The temperature of the sun's photosphere is around 5,500 degrees Celsius (9,932 degrees Fahrenheit). This is the visible surface of the sun and is where most of its light is emitted.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of re-emitted light in a transparent material is the same as the frequency of the light that stimulates its re-emission. This is due to the conservation of energy principle, where the energy of the absorbed photon is re-emitted as a photon of the same frequency.
Doppler effect with two people moving to each other?
In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.
Is heat emitted by the body at 200 celsius is twice the heat emitted by the body at 100 celsius?
Not at all. First of all, 200 Celsius is not double 100 Celsius. To make this kind of comparisons, you have to use an absolute scale, i.e., Kelvin. 200 Celsius = 473K; 100 Celsius = 373K, so that is only about a 27% increase. Second, the energy emitted by a hot body is (roughly?) proportional to the 4th. power of the temperature. Raising the ratio to the fourth power gives you a factor of about 2.59 - the hotter body will radiate 2.59 times as much heat energy as the cooler body.
Why does the sun emit higher frequency radiation than the earth does?
The sun emits higher frequency radiation than the Earth because it has a much higher surface temperature, around 5,500 degrees Celsius (9,932 degrees Fahrenheit). According to Wien's displacement law, the peak wavelength of radiation emitted by a black body is inversely proportional to its temperature; thus, the sun radiates primarily in the visible and ultraviolet spectrum. In contrast, the Earth, with a much lower average temperature of about 15 degrees Celsius (59 degrees Fahrenheit), emits radiation primarily in the infrared spectrum, which has longer wavelengths and lower frequencies.
What is the peak frequency of star?
The peak frequency of a star's emitted radiation depends on its temperature. A hotter star will emit more radiation at higher frequencies, while a cooler star will emit more at lower frequencies. The peak frequency can be estimated using Wien's law, which states that the peak frequency is inversely proportional to the star's temperature.
Which star will emit the shortest wavelength of its peak frequency?
The star emitting the shortest wavelength of its peak frequency will be a star with high temperature, such as a blue star. This is because the wavelength of light emitted by an object is inversely proportional to its temperature according to Wien's law.
