Going through past paper questions here is a list of the SQA recommended perfect answers

Using John Sharkey’s Flash Learning this video covers the required Virtual CfE Advanced Higher Physics Equations. NB there are some updates to equations since this material was produced.

I’ll add some more on other topics later.

We’d like to thank Mr S Bryce for providing these questions sorted by the topic.

Hi Folks! I had planned to finish these before the October hols! Sorry too much on. This is as far as I’ve got and I’ll update it a.s.a.p.

If you update it let me know. I’ll put the answers into a table of 2 columns so that if you fold down the middle they can be cue cards.

Type | Yr | Q No. | Answer |
---|---|---|---|

Trad | 2006 | 3 ai | Force exerted on 1 kg (of mass) placed in the field |

Trad | 2006 | 11 c | (Path length) in oil depends on angle of incidence or thickness ∴different colours are seen due to interference |

Trad | 2009 | 8 b | One tesla is the magnetic induction of a magnetic field in which a conductor of length one metre, carrying a current of one ampere (perpendicular) to the field is acted on by a force of one newton. |

Trad | 2009 | 9 ai | Division of amplitude is when some of the light reflects from the top of the air wedge and some is transmitted/refracted into the air. OR Some of the light is reflected from a surface of a new material/medium and some of the light is transmitted/refracted into the new material/medium. |

Trad | 2009 | 10 a | A stationary wave is caused by interference effects between the incident and reflected sound. |

Trad | 2009 | 10 b | The antinodes of the pattern are areas of maximum displacement/amplitude/disturbance The nodes of the pattern are areas of minimum/zero displacement/amplitude/disturbance |

Trad | 2010 | 4 a | Total angular momentum before (an event) = total angular momentum after (an event) in the absence of external torques |

Trad | 2010 | 6 bii | E-field is zero inside a hollow conductor. E-field has inverse square dependence outside the conductor. |

Trad | 2010 | 11 a | unpolarised light => Electric field vector oscillates or vibrates in all planes polarised light => Electric field vector oscillates or vibrates in one plane |

Trad | 2014 | 3 ai | The (minimum) velocity/speed that a mass must have to escape the gravitational field (of a planet). |

Trad | 2014 | 4 ai | The unbalanced force/ acceleration is proportional to the displacement of the object and act in the opposite direction. |

Rev | 2014 | 4 aii | The distance from the centre of a black hole at which not even light can escape. or The distance from the centre of a black hole to the event horizon. |

Trad | 2014 | 5 di | Electron orbits a nucleus / proton , Angular momentum quantised or Certain allowed orbits / discrete energy level |

Rev | 2014 | 6 aii | Photoelectric effect or Compton scattering Collision and transfer of energy |

Rev | 2014 | 6 di | Electron orbits a nucleus / proton (1) Angular momentum quantised (1) or Certain allowed orbits / discrete energy level |

Rev | 2014 | 8 a | The unbalanced force/ acceleration is proportional to the displacement of the object and act in the opposite direction. |

Trad | 2014 | 11c | Wavelengths in the middle of the visible spectrum not reflected or destructively interfere. Red and blue reflected / combined to (form purple). |

Trad | 2014 | 13 aii | The brightness would gradually reduce from a maximum at 0 degrees to no intensity at 90 degrees. It would then gradually increase in intensity from 90 degrees to 180 where it would again be at a maximum |

Rev | 2015 | 1 c | The speed of the mass will be less. Second mark for correct justification. eg: Flywheel has greater moment of inertia Flywheel will be more difficult to start moving Smaller acceleration of flywheel More energy required to achieve same angular velocity. |

Rev | 2015 | 2 a | Massive objects curve spacetime Other objects follow a curved path through this (distorted) spacetime |

Work will be done by the field on the mass. or A negative amount of work will be done to move an object from infinity to any point. or WD by gravity in moving to that point or Force acts in opposite direction to r. |

Rev | 2015 | 5 aiii | Difficult scale to read/information from diagram can only be read to 1 s.f. |

Rev | 2015 | 6 ai | Force acting on (acceleration of) object is directly proportional to and in the opposite direction to its displacement. (from equilibrium) |

Rev | 2015 | 7 aii | l reduced (or f increased) for X-rays or >E transferred D x reduced for X-rays since D x D p ³ h/4 p D p increases |

Rev | 2015 | 7 b | since DEDt³ h/4 p Borrowing energy for a short period of time allows particles to escape |
