Use the universal wave equation,
v=fxlambda
where v is velocity/speed
f is frequency
and lambda is wavelength
v=(500)(0.5)= 250 m/s
AnswerSpeed of a wave = Wavelength x frequencyv = 0.5 x 500v = 250 m/sAnswerIf it is an electromagnetic wave, then the speed is that of light - 'c (in vacuum)'.
500 hertz
Note: The speed should be in units of cm/s rather than cm. The relation between the speed (v), frequency (f) and wavelength (λ) is: v = fλ. Therefore, f = v/λ = (500 cm/s) / (20 cm) = 25 Hz.
C/lamba = 5.99584916e14 Hz
At 20 degrees Celsius or 68 degrees Fahrenheit the speed of sound c = 343 m/s. Wavelength lamda is 0.667 meters. Frequency f = c / lambda = 343 / 0.667 = 514.24 Hz.

Wavelength = (speed) / (frequency) = (5,000) / (10) = 500 meters = 0.5 km.
500 hertz
The speed of sound varies with temperature. At commonly experienced temperatures, it's about 343 meters/sec. Frequency = speed/wavelength = 343/0.686 = 500 Hz

There should be a note somewhere on the oven stating the frequency of the waves produced. It's normally around 2.5gigahertz. You can use this to workout the wavelength. The speed of the microwaves is the same as the speed of light, 3x10 to power of 8 metres per second. To get the wavelength you divide the speed by the frequency; 300 000 000m/s divided by 2 500 000 000waves/s which gives 0.12metres or 12cm.
No, the speed of sound may be 340 meters per second.The frequency is speed of sound divided by wavelength.So your frequency f = 340 / 0.68 = 500 Hz.
The equation needed is: V=fl Where V is the speed, f is the frequency and l is the wavelength. (the poxy thing won't let me enter a lamba sign) The key bit of information is "in a vacuum"; all waves in a vacuum travel at the same speed, 3x108ms-1. This is more commenly refered to as the speed of light, C. Therefore, f = V / l= C / l = 3x108 / 400x10-9 = 7.5x1014 Hz (Not in standard form that's: 750,000,000,000,000 Hz) (The '/' means divided by)
C=λv 340 m/s= 20 1/sec (λ) v= 17 m= ~56 ft
