• v = fλ

• v = λ/f

What does the symbol 'λ' represent in the equations provided?

• Frequency

What is a standing wave?

• A wave that travels in one direction without interference

• A pattern resulting from two waves of the same frequency, wavelength, and amplitude traveling in opposite directions

• A wave that changes frequency over time

• A wave that only travels through solids

What is a node in a standing wave?

• A point of maximum amplitude

• A point that always undergoes complete destructive interference

• A point where two waves meet and amplify

• A point that moves with the wave

What is an anti-node in a standing wave?

• A point of zero amplitude

• A point halfway between two nodes with the largest amplitude

• A point where waves cancel each other out

• A point that does not exist in standing waves
