When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s.
3 x10^8 m/s = wavelength/104.9 x 10^6 Hz (Hertz is 1/s)
wavelength = 2.86 meters
Answer:
gravity & inertia
Explanation:
what goes up must come down & an object in motion will stay in motion until stopped
Answer:
false, they are more reliable.
Explanation:
i had to do it last year.
If light travels 290,000,000 meters in 1 second, simply divide 1 second by 290,000,000 to find the time it takes to travel 1 meter.
1 / 290,000,000 = 0.000000003448 seconds (<em>or 3.5 nano seconds</em>)
Answer:
When radius of star increase by 6 factor then area of star will increase by a factor of 36.
Explanation:
As we know that
Area of star A given as
Where R is the radius of star.
Area of star when radius become 6 times
So
We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.
