Properties of Waves and Calculating Wave Speed

The video tutorial explains wave properties, focusing on amplitude, wavelength, frequency, and period. It distinguishes between transverse and longitudinal waves, highlighting their unique characteristics. The tutorial also covers wave speed calculation using the formula v = fλ, with practical examples involving sound waves and microwaves. Key concepts include the relationship between frequency and period, and the conversion of units for accurate calculations.

What is the amplitude of a wave?

• The maximum displacement from the undisturbed position

• The distance between two adjacent peaks

• The number of waves passing a point each second

• The time taken for one complete oscillation

How is the wavelength of a longitudinal wave typically measured?

• Distance between two adjacent rarefactions

• Distance between two adjacent compressions

• Distance between two adjacent troughs

• Distance between two adjacent peaks

What is the relationship between period and frequency?

• Period equals frequency divided by wavelength

• Period equals 1 over frequency

• Period equals frequency times wavelength

• Period equals frequency plus wavelength

If a sound wave travels through rock at 6000 m/s with a frequency of 500 Hz, what is its wavelength?

• 10 meters

• 20 meters

• 12 meters

• 15 meters

What is the speed of microwaves in water if their wavelength is 5 cm and frequency is 4 GHz?

• 2.5 x 10^8 m/s

• 1.5 x 10^8 m/s

• 3.0 x 10^8 m/s

• 2.0 x 10^8 m/s
