1. A wavelength of 5 has a speed (velcocity) of 20 m/s. What is the frequency?first question

2. A wave with wavelength of 25 has a frequency of 30. What is the speed (velocity) of the wave?

3.A wavelength of 2 has a speed (velocity) of 100 m/s. What is the frequency?

4.A wave with velocity of 50 m/s has a frequency of 2Hz. What is the wavelength?

5.A wave with velocity of 250 m/s has a frequency of 5Hz. What is the wavelength?

Someone please answer all of these i will mark you as brainliest oh and this is 8th grade math some make it as 8th grade math
