Hello everybody I have a question about light (a laser) and speed. Let's assume a object (space probe) traveling in a constant motion that haze a vacuum inside itself.
Now there are 4 lasers groped in pairs of 2 in south a way that both lasers in a group are connected with both their ends together (The lasers are identical ). Now group A is pointing along the vector of movement of the probe and group B is flipped 90 degrees from group B.
I have picked lasers because they emit a farley non dispersing light compared to a flashlight. Now What is going to happen if the probe is traveling ½ c ? What will the lasers indicate ?
I assume that group A would indicate the exact speed of the probe because the blue shift of the laser light would be if a observer would look in the direction of the movement and a red shift if he would look in the opposite way. And the group B would do the same thing because if you would measure with a ruler from the one of the lasers to the top or bottom of the probe you would see that the lasses dot is a little of and this would correspond to the direction and speed of the probe. Are my assumptions correct ? Thank you for your responses.
