**After exercising, your heart beats about 2 times per**second.What is the frequency?What is the period?**What is the velocity of a water wave if the frequency is 5**Hz and the wavelength is 12 m?**A wave’s period is 0.25 seconds. What’s its**frequency?What’s its speed if the wavelength is 2 meters?**A pendulum completes one cycle in 4 seconds.What is the**frequency?What is the period?**After exercising, your heart beats about 2 times per**second.What is the frequency?What is the period?**A sound wave has a velocity of 343 m/s. Calculate its**frequency if the wavelength is 175 m**WIBC broadcasts at 93.1 MHz. That’s 93,100,000 Hz. The**speed of radio waves is 300,000,000 m/s. What is the wavelength of the WIBC broadcast?**What is the speed of a wave if its wavelength is 20 meters**and its frequency is 50 Hz?**What is the velocity of a water wave if the frequency is 5**Hz and the wavelength is 12 m?**You’re playing jump rope. You make your arm go up and**down 3 times per second. The distance between you and your partner (half of the wavelength) is 4 meters. What is the wave speed?**What is the wavelength of a water wave if its frequency is 5**Hz and its velocity is 35 m/s?**You’re on a boat. The crest of the incoming waves pass**you every 10 seconds. The waves travel at5 m/s. What is they’re wavelength
