if two lighting volts heat exactly same place at the same time in are frame of ref,it is possible that observes in other frames will see the volts heating at def. time or diff. places? explain
According to the theory of relativity, the observation of events can be influenced by the relative motion between observers. This means that different observers in different frames of reference may perceive the same event differently.
In the scenario you described, if two lightning bolts were to strike the same place simultaneously in one frame of reference (let's call it Frame A), and there are observers in other frames of reference (Frame B, C, etc.), the perception of the lightning bolts can indeed be different.
From the perspective of an observer in Frame A, who sees both lightning bolts strike the same spot simultaneously, they will perceive the bolts heating at the same time and location.
However, an observer in Frame B, moving relative to Frame A, might perceive a different sequence of events due to the relative motion. For example, if Frame B is moving towards the lightning bolts, the observer in Frame B may perceive one bolt hitting the location slightly before the other bolt. Conversely, if Frame B is moving away from the lightning bolts, the observer in Frame B may perceive both bolts hitting the location slightly after each other.
It's important to note that these differences in perception arise due to the relativity of simultaneity and the relativistic effects of time dilation and length contraction. While the underlying physical event of two bolts striking simultaneously remains the same for all observers, their relative motion can lead to differences in how they perceive the events.
To answer this question, we need to take into account the principles of special relativity. According to special relativity, the speed of light is constant and the same for all observers, regardless of their motion relative to the source of light. Let's break down the scenario:
In the rest frame (frame of reference) where the observer is located, two lightning bolts strike the same place at the same time. Since the observer is stationary relative to the event, they will perceive the lightning bolts hitting the same spot simultaneously in their frame of reference.
However, when we consider a different frame of reference, where the observer is in motion relative to the lightning bolts, the situation changes. Special relativity tells us that if two events are simultaneous in one frame of reference, they will not necessarily be simultaneous in a different frame that is moving relative to the first.
In the moving frame, due to the relative motion between the observer and the lightning bolts, the observer might perceive one of the bolts hitting before the other. This apparent time difference is known as a time dilation effect. Additionally, due to the contraction of lengths in the direction of motion (known as length contraction), the observer may see the two bolts hitting different places.
The amount of time dilation and length contraction observed depends on the relative velocity between the observer and the lightning bolts. As the relative speed approaches the speed of light, these effects become more pronounced.
In summary, from the perspective of a stationary observer, the two lightning bolts will hit the same place at the same time. But from the perspective of an observer in a different frame of reference moving relative to the lightning bolts, the bolts may appear to hit at different times or locations due to the effects of special relativity.
