A bright red light represents a relatively short wavelength and relatively short amplitude. This is represented by options A and D.

Bright red lights represent light moving away from the observer (popularly known as redshift), meaning a short wavelength is emitted.

Amplitude in waves represents their frequencies and intensities. Bright red lights have a relatively short amplitude.

Answer:

The correct phrases to describe a wave of a bright red light are A. Relatively short wavelength and D. Relatively short amplitude

Explanation:

When light waves move away from an observer, they experience a shift in frequency known as the Doppler effect. If the light source is moving away from the observer, the wavelength of the light appears to be longer, or redshifted. However, this effect is generally not observable in everyday situations with stationary light sources.

Regarding the amplitude of the wave, it actually represents the intensity of the light rather than its frequency. A bright red light is indeed associated with a relatively high intensity, which corresponds to a relatively tall amplitude. Therefore, options A and D are the correct phrases to describe a wave of a bright red light.When light waves move away from an observer, they experience a shift in frequency known as the Doppler effect.
