BTEC Applied Science Unit 1: Physics 2024 (Graded)

BTEC Applied Science Unit 1: Physics 2024 (Graded) Amplitude - Correct answer-The maximum value of displacement in the oscillation cycle Displacement - Correct answer-How far the quantity has moved from its rest value at any given time Period - Correct answer-The time taken for one whole cycle of an oscillation Oscillation - Correct answer-A regularly repeating motion about a central value Wave speed equation - Correct answer-Wave speed = frequency x wavelength / v=fλ Transverse waves - Correct answer-The displacement of the wave is at right angles to the direction of wave travel Longitudinal waves - Correct answer-The displacement of the wave is parallel tot he direction of wave travel Stationary waves - Correct answer-Two waves travelling in opposite directions/ energy is trapped in pockets Name the types of stationary waves from smallest to largest - Correct answer-1st harmonic (fundamental), 2nd harmonic, 3rd harmonic, 4th harmonic What is the wavelength of a 1st harmonic stationary wave - Correct answer-1/2 a wavelength / 1/2λ What is the wavelength of a 2nd harmonic stationary wave - Correct answer-1 wavelength / λ What is the wavelength of a 3rd harmonic wavelength - Correct answer-1.5 wavelengths / 3/2λ What is the wavelength of a 4th harmonic wavelength - Correct answer-2 wavelengths / 2λ Label a node and anti-node on a stationary wave - Correct answer-Node is the stationary part on a wave (the middle bit) and the anti-node is the part in motion (the highest or lowest points on the wave) Stationary waves in a tube - Correct answer-There are anti-nodes and each end of the tube BTEC Applied Science Unit 1: Physics How to draw a stationary wave in a tube - Correct answer-Start the wave at the top corner on the tube and then draw it down and bounce back off the bottom and repeat for the amount of waves that you need. Stationary waves in a closed end tube - Correct answer-There is a node at the closed end How to draw a stationary wave in a closed end tube - Correct answer-Start with the wave in the middle of the closed end, draw the wave going down and then up to the top and back to the rest position in the middle and then repeat for the amount of waves that you need
