Verified step by step guidance

Understand the Doppler Effect: The Doppler Effect refers to the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source. It applies to all types of waves, including sound and light.

Identify the effect on light: For light waves, the Doppler Effect results in a shift in the frequency and wavelength of the light observed. This shift is known as the redshift or blueshift, depending on the direction of the source's motion.

Determine the direction of motion: If the light source is moving away from the observer, the wavelengths are stretched, leading to a redshift. Conversely, if the source is moving towards the observer, the wavelengths are compressed, resulting in a blueshift.

Analyze the given statements: The statement 'The Doppler Effect causes light from a receding source to shift towards the red end of the spectrum' is correct because it describes the redshift phenomenon accurately.

Clarify misconceptions: The statement 'The Doppler Effect causes light from a receding source to shift towards the blue end of the spectrum' is incorrect because a receding source causes a redshift, not a blueshift.
