    In the theory of relativity, the Lorentz contraction formula

    upload_2022-5-8_19-38-1.jpeg

    expresses the length L of an object as a function of its velocity v with respect to an observer, where L0 is the length of the object at rest and c is the speed of light.
    Find lim(v→c− L and interpret the result. Why is a left hand limit necessary?

    A left hand limit is necessary because the velocity cannot be greater than the speed of light.

    and since we know c > 0

    upload_2022-5-8_19-43-13.jpeg

    Now, as upload_2022-5-8_19-44-1.jpeg

    So. =0

    thus, upload_2022-5-8_19-45-29.jpeg

    As the object’s velocity increases towards c, it’s length decreases towards 0.

    Thank you so much. I had no idea that this question is so involved. You said the following:

    So. = 0.

    What = 0?

    c^2-v^2=0 because v^2->c^2

    Ok. I see what you mean.

    How about the link below? I tried it failed to understand how it's done.

    Find Delta...2
