Chapter 35: Problem 1

The most important fact we learned about aether is that: a) It was experimentally proven not to exist. b) Its existence was proven experimentally. c) It transmits light in all directions equally. d) It transmits light faster in longitudinal direction. e) It transmits light slower in longitudinal direction.

Short Answer

Expert verified
Answer: It was experimentally proven not to exist.

Step by step solution

01

Understanding the concept of aether

The concept of aether was introduced in ancient Greek philosophy, and it was believed to be an invisible medium that filled space and helped propagate light waves. However, multiple attempts to prove its existence have failed.
02

Analyzing the given options

Now, let's analyze each option to find the most important fact about aether: a) It was experimentally proven not to exist. b) Its existence was proven experimentally. c) It transmits light in all directions equally. d) It transmits light faster in longitudinal direction. e) It transmits light slower in longitudinal direction.
03

Identifying the correct answer

Option (a) states that aether was experimentally proven not to exist. This is a reference to the famous Michelson-Morley experiment, which failed to detect aether and eventually led to the development of the special theory of relativity by Albert Einstein. This fact is a major turning point in the history of science, making this option the correct answer. Therefore, the most important fact we learned about aether is: a) It was experimentally proven not to exist.

Most popular questions from this chapter

A spaceship is traveling at two-thirds of the speed of light directly toward a stationary asteroid. If the spaceship turns on it headlights, what will be the speed of the light traveling from the spaceship to the asteroid as observed by a) someone on the spaceship? b) someone on the asteroid?

A meteor made of pure kryptonite (Yes, we know: There really isn't such a thing as kryptonite ...) is moving toward Earth. If the meteor eventually hits Earth, the impact will cause severe damage, threatening life as we know it. If a laser hits the meteor with wavelength \(560 \mathrm{nm}\), the entire meteor will blow up. The only laser powerful enough on Earth has a \(532-\mathrm{nm}\) wavelength. Scientists decide to launch the laser in a spacecraft and use special relativity to get the right wavelength. The meteor is moving very slowly, so there is no correction for relative velocities. At what speed does the spaceship need to move so the laser has the right wavelength, and should it travel toward or away from the meteor?

A spacecraft travels along a straight line from Earth to the Moon, a distance of \(3.84 \cdot 10^{8} \mathrm{~m}\). Its speed measured on Earth is \(0.50 c\). a) How long does the trip take, according to a clock on Earth? b) How long does the trip take, according to a clock on the spacecraft? c) Determine the distance between Earth and the Moon if it were measured by a person on the spacecraft.

The hot filament of the electron gun in a cathode ray tube releases electrons with nearly zero kinetic energy. The electrons are next accelerated under a potential difference of \(5.00 \mathrm{kV}\), before being steered toward the phosphor on the screen of the tube. a) Calculate the kinetic energy acquired by the electron under this accelerating potential difference. b) Is the electron moving at relativistic speed? c) What is the electron's total energy and momentum? (Give both values, relativistic and nonrelativistic, for both quantities.)

In Jules Verne's classic Around the World in Eighty Days, Phileas Fogg travels around the world in, according to his calculation, 81 days. Due to crossing the International Date Line he actually made it only 80 days. How fast would he have to go in order to have time dilation make 80 days to seem like \(81 ?\) (Of course, at this speed, it would take a lot less than even 1 day to get around the world \(\ldots . .)\)
