The wave number of the light emitted by a certain source is 2 x 108m-'. The wavelength of this light will be (a) 500 nm (b) 500 m (d) 5 x 10 m (c) 200 nm

Awave travels at a speed of 5.2 m/s. if the distance between crests is 0.40 m, what is the frequency of the wave? use f=v/wavelength a. 13 hz b. 2.1 hz c. 0.077 hz d. 5.6 hz

Why do different substances have diffrent properties

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?
