eqn: speed = wavelength * frequency

What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.30 m?

speed = 0.3*100 = 30m/s

What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

speed = 0.1*50 = 5m/s

What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

frequency = 20/0,5 = 40Hz

What is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m?

frequency = 80/0.2 = 400Hz

What is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m?

frequency = 120/0.4 = 300Hz

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 Hz?

wavelength = 340/440 = 0.7727m

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 Hz?

wavelength = 340/880 = 0.3864m

What is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 Hz?

wavelength = 250/400 = 0.625m

What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 2.0 m?

speed = 2*50 = 100m/s

What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.50 m?
speed = 0.5*100 = 50m/s

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
