The wavelength of a signal is calculated by c/f. C is the velocity of the wave and f the frequency of the signal.
Wavelength is defined as the distance between any two successive crests or troughs in case of a mechanical wave.
In case of longitudinal wave, the distance between two successive compressions or rarefactions will be the wavelength.
In case of electromagnetic wave c/f will be the wavelength

A blackbody curve relates the wavelength of emitted light to?
The temperature of the object.
When the temperature of an object increases would the wavelength of energy radiates increase or decrease?
Increase
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
What is the de Broglie wavelength in meters of a baseball weighing 145 and traveling at 152?
You can use De' Broglie's equation. I think it is wavelength = plank's constant/mass of the object *velocity.velocity is unknown in this case, m= 154g and wavelength is 0.450*10-90.450*10-9 = look up the value of plank's constant/ 0.145 kg* Velocity.Rearrange the equation to get velocity of an object.
What does Doppler shift in starlight give us?
The wavelength of light emitted by a moving object is shifted. To get it really right, you should understand the Special Theory of Relativity.
What will happen to an object wavelength as the object move toward you?
The wavelength will be shorter!
Can an object vibrate at the wavelength of light?
No object can vibrate at the wavelength of light. wavelength of light depends on the intensity of light and electron movements.
What did you observe about the wavelength and frequencies of the different colors of light?
A higher frequency means a shorter wavelength, and a lower frequency means a longer wavelength.
The wavelength of light used to observe an object must be ... than the object itself?
The wavelength of light used to observe an object must be shorter than the size of the object itself.
What will happen to an objects wavelength as the object moves toward you?
The wavelength will be compressed/shortened.
What is the wavelength of a 300 gram object moving at a velocity of about 100 mph?
The mass and velocity of an object do not determine its wavelength: it could be travelling in a straight line!
As a wave nears shore the wave height increases and the wavelength .?
[object Object]
When viewing an object we see its color according to the wavelength of light that the object?
refelcts
When an object is heated to higher temperatures what happens to its wavelength of emission?
the wavelength of emission becomes shorter
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant obect we say that the object's spectrum is?
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
Why is the statement the color of an object depends on the wavelengths of light it absords inaccurate?
...because the colour of an object depends on the wavelength of light it reflects, or the wavelength of light it emits.
If the frequency of the waves produced by a vibrating object increases how does the wavelength of the waves produced change?
The wavelength decreases. Frequency and wavelength are inversely related.
