# How Long Does a Meter Stick Appear When Traveling at Light Speed?

• Aprilshowers
In summary, the conversation discusses the use of a formula to determine the apparent length of a meter stick traveling at the speed of light relative to an observer. However, the formula does not provide a reasonable answer due to the fact that a meter stick cannot travel at the speed of light. The conversation also includes a subtle hint that the formula will not work.

I know the formula to use for this problem, but cannot seem to make
it come out with a reasonable answer. Can anyone help?

If a meter stick travels at the speed of light relative to an observer,
how long does the meter stick appear to the observer?

(I cannot seem to make the radical sign or the exponents look right,
but I will do my best!)
Formula: L=Lo (RADICAL SIGN) 1 -v(exponent 2) / c(exponent 2)

Thanks

Trick question. You should not *get* a reasonable answer. Why?

The root of your problem is that:

A meter stick can't travel at the speed of light relative to an observer.

Way to give a subtle hint man...

## 1. What is the meter stick problem?

The meter stick problem is a common physics problem that involves measuring the length of an object using a meter stick. It typically requires knowledge of basic concepts such as units of measurement and precision.

## 2. How do I solve the meter stick problem?

To solve the meter stick problem, you will need to carefully measure the length of the object using the meter stick and record the measurement to the appropriate precision. Then, you can use mathematical equations or concepts such as unit conversions to calculate the final answer.

## 3. What if I don't have a meter stick?

If you do not have a meter stick, you can use any other measuring tool with a known length, such as a ruler or tape measure, as long as you are consistent with the units of measurement and precision.

## 4. Can I estimate the measurement with the meter stick?

Yes, you can estimate the measurement using the meter stick if the object does not have a clear end point. However, it is important to note that the estimation will likely result in less precision and accuracy compared to a direct measurement.

## 5. What are some common mistakes when solving the meter stick problem?

Some common mistakes when solving the meter stick problem include using the wrong units of measurement, not recording the measurement to the appropriate precision, and not paying attention to the orientation of the meter stick when measuring the object.
