What else can I help you with?
At what point does time stop at the speed of light?
Time does not stop at the speed of light; rather, time appears to slow down for an object moving at the speed of light relative to an observer.
What happens to a shadow if you change the angle at which light shines on an object?
The shadow will change in size and shape, becoming longer or shorter depending on the angle of the light. The direction of the shadow will also shift based on the angle of the light source relative to the object.
How do shadows change size?
Shadows change size based on the position of the light source relative to the object casting the shadow. When the light source is closer to the object, the shadow appears larger, and when the light source is further away, the shadow appears smaller. The angle of the light hitting the object also affects the size of the shadow.
What happens to a shadow when the object is moved?
The shadow's position changes relative to the light source and object. It will move and change in size depending on the direction and distance the object is moved.
The Doppler effect indicates that the frequency of energy (sound or light) waves when an object is approaching and when an object is moving away?
The Doppler effect is the change in frequency of waves (such as sound or light) due to the relative motion between the source of the waves and the observer. When an object is approaching, the waves are compressed, causing a higher frequency, resulting in a higher pitch for sound waves or a blue shift for light waves. When an object is moving away, the waves are stretched, causing a lower frequency, resulting in a lower pitch for sound waves or a red shift for light waves.
Is an object that is not moving relative to Earth a blue shift?
No, an object not moving relative to Earth is not a blue shifted object. With no relative motion, an object will not be subject to Doppler effect and will not red or blue shift. For an object to be blue shifted, the distance between the object and Earth must be decreasing. The object must be closing on Earth or vice versa.
Wouldn't an object moving at the speed of light relative to other things in space technically be at rest relative to itself and always allowed to accelerate?
It would be if it wasn't for the fact that time relative the object moving at high speed slows down as you approached the speed of light, and completely stops when you reach it. This is what prevents things from going faster than the speed of light.
At what point does time stop at the speed of light?
Time does not stop at the speed of light; rather, time appears to slow down for an object moving at the speed of light relative to an observer.

Is there an equation that determines how much the relative time slows as an object approaches the speed of light.?
Time recorded on the moving clock = (non-moving time) multiplied by the square root of (1 - v2/c2). v = the speed of the moving clock c = the speed of light
What happens to a shadow when the object is moved?
The shadow's position changes relative to the light source and object. It will move and change in size depending on the direction and distance the object is moved.

Does the Doppler effect happen with light?
Yes, the Doppler effect can be applied to light. Any wave function can be subject to the Doppler effect if there is relative motion between the source and an observer. That's how we know that the Universe is expanding.
What causes the frequency of light from a moving object to change?
It is the Doppler effect that causes the apparent shift in the frequency of light or sound waves as the source and observer are moving farther apart or closer toward each other. Use the link below for more information.
What is a Doppler effects?
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the wave. This phenomenon is commonly experienced with sound waves (for example, the change in pitch of a siren as a car approaches and then passes by) and light waves (such as the shift in color of stars moving towards or away from Earth).
What is the name of the amount of light an object reflects relative to its surroundings?
The name of the amount of light an object reflects relative to its surroundings is "albedo." A higher albedo value indicates that an object reflects more light, while a lower albedo value means that it absorbs more light.
