What else can I help you with?
Why does a laser beam seem to have a finite end?
A laser beam appears to have a finite end because of the way light scatters and diverges over distance due to diffraction and dispersal. This phenomenon causes the light to spread out, making the beam appear to gradually fade away rather than continue indefinitely.
The velocity of light was first measured by?
The velocity of light was first measured by Ole Rømer, a Danish astronomer, in 1676. He used observations of the moons of Jupiter to deduce the finite speed of light.
What is an extended source of light?
An extended source of light refers to a light source that is not a point source, meaning it has a finite size and emits light over an area rather than from a single point. Examples include fluorescent tubes, incandescent bulbs, and the sun.
This theory by Albert Einstein explains why all observers have their own separate measure of time because of the finite speed of light?
The theory you are referring to is Einstein's theory of relativity, specifically the concept of time dilation. It states that time can pass at different rates for different observers depending on their relative motion and gravity. This is due to the finite speed of light as a constant in the universe.
How many images do you see through a pair of parallel mirrors?
It's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
How many image in 2 parallel mirrors?
It's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.
Do we see the universe now as it existed in the past?
True, since the speed of light is finite.
Why an explosion 100 light years away can be seen?
An explosion that occurs 100 light years away can be seen on Earth because light travels at a finite speed, so it takes time for the light from the explosion to reach us. Since the speed of light is finite, any event that occurs in the universe will have a delay in when we see it on Earth, depending on its distance.
How many images are seen when two mirrors are placed in parallel?
If they are back to back, only 1. ------------------------------------------------------ If they are face to face,it's not infinite, it's finite, because the speed of light is finite. Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
Is the number of asteroids over 0.5 miles?
It is a finite number.It is a finite number.It is a finite number.It is a finite number.
Is every subset of a finite set is a finite?
prove that every subset of a finite set is a finite set?
Use finite in a sentence?
There are a finite number of apartments. Finite numbers may be large or small. There are a finite number of states. The number of molds in my fridge is not exactly finite.
Is star is finite or infinite?
It is finite.
What is an example sentence for the word finite?
Coal is a finite resource on Earth.The finite resources will eventually run out.
What is the difference between finite and non finite?
finite is an object , and they are also singular in nature
Why a finite automaton is called finite?
I would guess that is because it has a finite number of different states. (It is also known as a finite-state machine.)
