What is the apparent change in frequency of a sound emitted by a moving object as it passes a stationarybobserver called?
The apparent change in frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. This effect causes the perceived frequency of the sound to change depending on the relative motion of the source and the observer – it is higher as the source approaches the observer and lower as it moves away.

The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary abserver?
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. As the object moves towards the observer, the observer perceives a higher frequency (higher pitch) than what is actually emitted. Conversely, as the object moves away from the observer, the perceived frequency is lower than the actual frequency emitted.
The apparent change in the frequency of a sound emitted by a moving object?
The apparent change in the frequency of a sound emitted by a moving object is known as the Doppler effect. When the object is moving towards an observer, the frequency is perceived as higher (pitched up), and when the object is moving away, the frequency is perceived as lower (pitched down). This effect is commonly experienced with passing vehicles or sirens.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect?
Doppler effect.
What is the name of the apparent change in a pitch of a moving source called?
The apparent change in pitch of a moving sound source is called the Doppler effect. It describes how the frequency of the sound waves perceived by an observer changes as the source of the waves moves relative to the observer.
The apparent change in frequency as a wave source moves in relation to the listener is called?
The Doppler effect is that apparent change of the frequency of a moving object when someone is stationary. A car may seem to get louder as it gets closer to a person and then the sound will drop as the car gets away.

How did Einstein used Plank' theory to explain the existence of threshold frequency?
Einstein used Planck's theory of quantization to explain the photoelectric effect by proposing that light is quantized into packets of energy called photons. These photons have energy proportional to their frequency, and when light with frequency below the threshold frequency interacts with a metal surface, no electrons are emitted. Above the threshold frequency, each photon can transfer enough energy to overcome the work function of the metal, causing electrons to be emitted.

What kind of electromagnetic energy consists of photons with the highest frequency?
The highest frequency electromagnetic waves are called gamma rays. The waves are emitted from nuclei .
How does the frequency of light emitted depend upon the temperature?
The black body equation describes this in detail, it is called Plank's law. All bodies emit electromagnetic radiation. The hotter the body the higher the average frequency. Refer to the links in the Related links for lots of detail.
What happens to the frequency of light emitted from the vicinity of a black hole Why and What happens to the frequency of light falling into a black hole What would you call this effect?
When light is traveling away from a black hole, its wavelength becomes longer. This is called blue-shifting. If it's going in, the wavelength becomes shorter, which is called red-shifting.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
