Is stroboscopic effect in incandescent lamps?
The stroboscopic effect is caused by the flickering of light at a frequency that can appear as slow motion or frozen movement. Incandescent lamps do not typically exhibit this effect because they emit a continuous spectrum of light without noticeable flickering like some other light sources.
The Doppler Effect is a phenomenon that allows one to measure an object's Select one a. temperature. b. radial motion. c. radius. d. chemical composition.?
b. radial motion. The Doppler Effect can be used to measure an object's radial motion by analyzing the shift in the frequency of the waves emitted by the object as it moves towards or away from the observer.
Which force needs to touch something to have an effect?
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
What law of motion allowed you to move through the air?
The law of motion that allows objects to move through the air is Newton's First Law of Motion, also known as the Law of Inertia. This law states that an object in motion will stay in motion unless acted upon by an external force. In the case of a person moving through the air, the force propelling them forward is typically generated by their own muscles or external sources like wind or a machine.
What does the Doppler effect look like?
The Doppler effect describes how the frequency of a wave changes depending on the relative motion between the source of the wave and the observer. For sound waves, this effect causes a change in pitch as the source moves towards or away from the observer. For light waves, the Doppler effect causes a shift in color towards the blue end of the spectrum as objects move towards an observer and towards the red end as they move away.

What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
What is the evidence of motion of the universe?
The most important piece of evidence that shows that the universe is in motion is the Doppler Effect, also termed the red shift. This basically means that objects headed away the observer will have their light bent toward the "red" (lower frequency) side of the light spectrum while objects headed toward the observer will have their light bent toward the "blue" (higher frequency) end of the spectrum. By using the Doppler Effect we are able to that the majority of the universe is in motion, expanding outward.

What is the effect of motion?
Movement?
How does the speed of the star affect the spectrum?
The speed of a star affects its spectrum through the Doppler effect. If a star is moving towards or away from us, the wavelengths of the light it emits will be shifted towards the blue (blue shift) or red (red shift) end of the spectrum, respectively. This shift can provide information about the star's velocity and direction of motion.
What did the spectral lines of the five galaxies reveal about their motion relative to earth?
The spectral lines of the five galaxies revealed their motion relative to Earth through the Doppler effect, which shows shifts in wavelength. If the lines were shifted toward the red end of the spectrum, it indicated that the galaxies are moving away from Earth, suggesting the expansion of the universe. Conversely, blue shifts would indicate that the galaxies are moving closer. Analyzing these shifts allows astronomers to determine the velocities and distances of these galaxies.
How does the Doppler effect affect starlight?
The Doppler effect can shift the wavelengths of light emitted by stars towards the red or blue end of the spectrum, known as redshift or blueshift, respectively. This shift in wavelength can indicate whether a star is moving away from or towards Earth, providing information about its velocity and direction of motion.
What is the cause and effect of the three laws of motion?
They are unrelated to "cause and effect".
How does projectile motion compare with Magnus effect?
Projectile motion refers to the motion of an object moving through a gravitational field, such as a ball thrown in the air. The Magnus effect, on the other hand, is a phenomenon where a spinning object experiences a sideways force perpendicular to its direction of motion, affecting its trajectory. In essence, projectile motion is a general term for the motion of objects in a gravitational field, while the Magnus effect is a specific effect caused by rotation.
What are 3 things that we can learn about a star by observing it's spectrum?
By observing far away stars in our galaxy through a spectroscope, we are able to see the spectrum that appears from the substances in these stars. Each element has a unique spectrum when light is shone through it, so we are able to determine what elements make up certain stars.
