There are not 5 colors in a rainbow, but 7- red, orange, yellow, green, blue, indigo, and violet.
1 - Red 2 - Orange 3 - Yellow 4 - Green 5 - Aquamarine 6 - Blue 7 - Violet
they were the colors chosen by the IOS to represent the 5 countries. Australia, Africa, Asia, Europe and America.
I can resolve 100 arc seconds. If craters are 60 arc seconds I'd bet that there are people whose eyes are good enough. 60 arc seconds is certainly within the 20 arc second maximum capability of the eye.
Athena Stefanopoulos is 5' 5".
velocity = frequency × wavelength frequency = velocity / wavelength f= 100 /20 f= 5 Hz
Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m
The frequency is 1/5 = 0.2 Hertz. The wavelength is irrelevant in this question.
The answer is in the question! 5 Hz Also, a wavelength cannot be 5 cycles - wrong units.
Always the lower wavelength lambda has a higher frequency f and the higher wavelength has the lower frequency. Speed of medium c = lambda times frequency f = c / wavelength lambda = c / f The wavelength 1x10-5 meters has a higher frequency than the wavelength 1x10-7 meters.
Speed = (frequency) x (wavelength) = (5) x (3 cm) = 15 cm/sec
Electromagnetic wavelength = speed/frequency = 3 x 108/6 x 1010 = 5 mm
Just divide the speed by the frequency. Since SI units are used, the wavelength will be in meters.
5 inches
The speed of a wave = (frequency) x (wavelength) = 2.5 meters per second.
Wavelength = (speed) / (frequency) = 299,000,000 / 5 = 59,800,000 meters = about 37,000 milesThis is no X-ray. It's a longer wavelength (lower frequency) than any electrical signal we generatefor any purpose.The longest wavelength that's called an X-ray is in the neighborhood of 0.00000001 meter.Its frequency is 30,000,000,000,000,000 Hz.
That depends, what wave you are talking about. The general relationship is: speed (of the wave) = frequency x wavelength. Solving for frequency: frequency = speed / wavelength If you are talking about an electromagnetic wave in a vacuum, the speed is about 300,000,000 meters/second. Other waves, however, can have quite different speeds.
