3.6 Describe selected properties and applications of EMR, radioactive decay, sound and ultrasound
Key tips
- Show all working of your calculations including any rearrangement of formulae.
- Understand scientific notation.
- Be aware of the appropriate use of units. You may use both negative index (for example, m s-2) and slash notation (for example, m/s2) when writing units. However, the examination paper will supply data using negative index notation.
- Don't forget to do sensible rounding in solving problems.
