It seems you're referencing the Doppler effect, which describes how the frequency of waves changes in relation to an observer moving relative to a source. Here's how the concepts fit together based on your description:
-
When a vibrating object is moving away from an observer: The frequency of the vibrations measured by the observer will be lower than the actual frequency of the vibrating object. This is known as redshift in terms of light frequencies.
-
When the object and observer are both stationary: If the vibrating object is moving and the observer is stationary, the frequency observed will be altered based on the relative motion. If the object is moving toward the observer, the observed frequency will be higher than the actual frequency.
-
When a source of light (like a star) is moving toward an observer on Earth: The light spectrum of that star will appear "bluer" (higher frequency) compared to the light spectrum of the Sun. This effect is called blueshift.
In summary, for your sentences:
- "Vibrating object is moving away from the observer" → lower frequency.
- "Vibrating object is moving toward the observer" → higher frequency.
- "Light spectrum of the star will appear bluer (higher frequency) compared to the light spectrum of the Sun if it is moving toward the observer."
