Question 1

find the other item.

Answer 1

• 2.76 Hz = 0.36 sec
• 11.8 sec = 0.085 Hz
• 0.436 kHz = 2.29 x 10^-3 sec
• 5/8 sec = 8/5 Hz

Question 2

what are the frequency and velocity of a wave where wavelength = 0.787 m and period = 2.65 sec?

Answer 2

frequency = 0.3773 Hz

and

velocity = 0.297 m/s a.f.s.

Question 3

what are the wavelength and period of a wave moving at 376 cm/s a.f.s. @ 808 cHz?

Answer 3

period = 0.124 sec

wavelength = 46.5 cm

(note: photo should read T = 1/8.08 = 0.124
