Yes, it is.
Increasing wavelength is an indication of a Doppler shift caused by an object moving away from the viewer. Longer wavelengths (of the visible spectrum) are redder, shorter wavelengths are bluer. Objects moving away from you have a red shift, objects moving toward you have a blue shift.
That depends which way you are moving along the electromagnetic spectrum.If you are moving from low to high frequency, then the last category before visible light is infrared radiation.If you are moving from short to long wavelength, then the last category before visible light is ultraviolet radiation.
a cold front is the fastest moving front
If the wavelength decreases, the spectral line moves towards the blue end of the visible light spectrum. This phenomenon is known as blue shift, indicating that the object is moving towards Earth.
redshift is what happens when visible light gets longer in wavelength, thus shifting toward the red end of the spectrum of visible light. This is a phenomenon that occurs when the light source is moving away from the observer.

The EM spectrum includes visible light. If an object moving very fast comes toward a reference point, the visible light radiating off it/reflecting off it gets "squashed": the wavelengths become shorter. This makes the visible light accquire a blue tinge. The opposite happens for an object heading away, and it looks more red.
When the wavelength of spectral lines emitted from an object decreases, it moves towards the violet end of the visible light spectrum. This is known as a blueshift, indicating that the object emitting the light is moving towards Earth.
When the wavelength of a spectral line emitted from an object decreases, it moves toward the blue end of the visible light spectrum. This phenomenon indicates that the object is moving toward Earth, a scenario known as blue shift. Common examples include distant galaxies or stars that are moving closer to us.
Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
As light waves move from red to violet along the visible spectrum, their wavelengths decrease and their frequencies increase. Red light has longer wavelengths and lower frequencies, while violet light has shorter wavelengths and higher frequencies. This shift in wavelength is perceived as a shift in color by our eyes.
