|---|---|---|---|---|---|
| show | The maximum displacement from the undisturbed portion of the wave to the crest
🗑
|
||||
| show | The number of waves per second
🗑
|
||||
| show | The time it takes for one wave to pass. Can be measured from peak to peak, trough to trough
🗑
|
||||
| What is the wavelength? | show 🗑
|
||||
| Name all the types of radiotion in the electromagnetic spectrum in order from longest to shortest wavelength | show 🗑
|
||||
| show | Radio (music), television and mobile phone signals
🗑
|
||||
| Give 2 uses for microwaves | show 🗑
|
||||
| show | Night Vision, Data transfer (e.g. mobile phones)
🗑

| What is so dangerous about U/V light? | show 🗑
|
||||
| show | Producing images of the skeleton
🗑

||||
| Give 2 uses for gamma rays | show 🗑
|
||||
| show | They can make cells mutate and therfore induce cancer
🗑
|
||||
| show | Velocity = frequency x wavelength (lambda)
🗑
|
||||
| What is the diference between light and sound? | show 🗑
|
||||
| show | displacement of molecules
🗑
|
||||
| What are standing waves? | show 🗑
|
||||
| show | The leading edge of a single pulse
🗑
|
||||
| What is superposition? | show 🗑
|
||||
| show | of the same frequency and with a constant phase relationship
🗑
|
||||
| In a standing wave what is a node or anti-node? | show 🗑
|
||||
| What are resonant frequencies? | show 🗑
|
||||
| show | The lowest resonant frequency that can be produced, i.e. one standing wave
🗑
|
||||
| show | The string vibrating itself affects very little air (not much air is displaced). The sound box resonates with the string meaning more air is displaced so a louder sound
🗑
|
||||
| show | lambda = 2l where l is the length of the string/tube
🗑
|
||||
| show | speed
🗑
|
||||
| How does the mass-per-unit length of a string affect the speed | show 🗑
|
||||
| Give the equation that relates speed, tension and mass-per-unit length | show 🗑
|
||||
| What is phase difference? | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
