Quiz Round 1: Physics & Space
28 July 2020
Our three contestants each took on a set of physics & space questions - but how well can you do? Answers at the bottom!
- Schrodinger’s famous cat thought experiment was produced in correspondence with which famous physicist? (Take a guess!)
- If the source of a wave is moving towards you, does the wave's frequency get higher or lower?
- Name any two of the four fundamental forces in physics.
- What’s the standard unit for measuring energy?
- A torque is what kind of force?
- A solenoid is a kind of electromagnet, made out of metal in what shape?
- Whose law states that the farther away a galaxy is from the Earth, the faster it is moving away from the Earth? He's also got a famous telescope!
- The brightest and most energetic events observed in the universe are bursts of what type of radiation?
- Who was the first person to reach outer space?
- What percent of the actual universe is the visible universe?
- The Twin Paradox is a thought experiment where a twin ends up younger than their sibling after taking a high-speed spaceship journey. What physics phenomenon is it describing?

- What fundamental particle is the most recent one to have been discovered - in 2012?
- What is the standard unit for measuring temperature?
- If you have a lightbulb powered by a circuit, and you add a second lightbulb in parallel with the first, what will happen to the brightness of the original bulb?
- How many poles does a magnet have?
- What do you call the boundary around something like a black hole, where anything happening beyond that boundary can’t affect in any way an outside observer?
