For the Doppler effect to occur what has to happen?
The Doppler effect is defined as an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
What must happen for acceleration to occur?
For acceleration to occur, there must be a change in an object's velocity over time. This change can happen by increasing or decreasing the object's speed or by changing its direction of motion. In essence, acceleration is a measure of how much an object's velocity changes per unit of time.
What must happen to the temperature of the liquid for vaporization to occur?
The temperature of the liquid must reach its boiling point for vaporization to occur. This is when the liquid molecules have enough energy to overcome the intermolecular forces holding them together and escape into the gas phase.
What is the Doppler effect. How might the Doppler effect be used to measure velocity?
Doppler effect is a effect of a sound that comes from moving object. Sound travels at the speed of 343 meters per second in dry air at 20 degree Celsius. Suppose the object is coming you with high speed the sound waves will get compressed. If the object goes away from you with high speed the sound waves will get diluted. You must have noticed a vehicle with siren coming to you and going away from you. The pitch of the sound is different in both the cases. The computer can give you the real time calculation of the speed. speed can be calculated by the computer in very short duration of the span. May be second or two. This phenomena is widely used to locate the speed of the moving object. In the medical field, it is very valuable tool. The speed of blood flow can be transformed into different colors. Like in color Doppler ultrasound examinations.
What must happen to some of the molecules in the air for a spark to occur?
Some of the molecules in the air must be ionized, meaning they lose or gain electrons, to create charged particles that can conduct electricity. When these charged particles accumulate enough energy, a spark can occur due to the flow of current through the air.
For the Doppler effect to occur?
For the Doppler effect to occur the measured object must be in motion (radial velocity) relative to the emitter of a wave.
For the Doppler effect to occur what has to happen?
