Who developed the theory of special relativity in 1905?

• Albert Einstein

• Isaac Newton

• Galileo Galilei

• Niels Bohr

According to Einstein's postulates, how does the speed of light behave in inertial reference frames?

• It varies with the speed of the source.

• It is the same in all inertial reference frames.

• It is faster in moving frames.

• It slows down in stationary frames.

In the Snap Lab experiment, what is the purpose of placing a slice of bread in the microwave?

• To measure the temperature of the microwave.

• To observe the color change in the bread.

• To measure the speed of light using the pattern on the bread.

• To test the microwave's power settings.

What is the result of using a stopwatch to measure time without electronic detection?

• It is more accurate.

• It is less accurate due to human reaction times.

• It is faster.

• It is slower.

What does Einstein's theory say about the speed of light?

• It varies with the observer's speed.

• It is constant and does not depend on the observer's speed.

• It is faster than any other speed.

• It is slower than sound.

What does Observer A see when the train moves towards Observer B?

• Observer A sees the bulbs flash at different times.

• Observer A sees the bulbs flash simultaneously.

• Observer A sees only one bulb flash.

• Observer A sees no flashes at all.

What is the formula for velocity as mentioned in the text?

• v = d + t

• v = d - t

• v = d / t

• v = t / d

Which field finds the theory of general relativity most useful?

• Nuclear physics

• Quantum chemistry

• Astrophysics

• Biology

An astronaut on the moon receives a message from mission control on Earth. The signal is sent by a form of electromagnetic radiation and takes 1.28 s to travel the distance between Earth and the moon. What is the distance from Earth to the moon?

• 2.34×10^5 km

• 2.34×10^8 km

• 3.84×10^5 km

• 3.84×10^8 km

If Michelson and Morley had observed the interference pattern shift in their interferometer, what would that have indicated?

• The speed of light is the same in all frames of reference.

• The speed of light depends on the motion relative to the ether.

• The speed of light changes upon reflection from a surface.

• The speed of light in vacuum is less than 3.00×10^8 m/s.
