Awater wave is generated in a ripple tank by an oscillator that vibrates 50 times in 30 seconds. a given trough of the wave travels 50.0 cm in 15 seconds. what is the wavelength of the water wave? produce all your workings.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?

Consider an air-filled charged capacitor. how can its capacitance be increased?

When doing scientific research ,the sources used should be ?
