As per the question the wavelength of the microwave is given as 3.52 mm.
we are asked to calculate the frequency of the wave.
we know that microwave is a electromagnetic wave.
As per Clark Maxwell's electromagnetic theory ,every electromagnetic wave moves with a velocity equal to the velocity of light in vacuum and that is equal to 3×10^8 m/s.
From the equation of the wave,we know that velocity of wave is the product of frequency and wavelength.
Mathematically wave velocity where f is the frequency of the wave and is the wavelength.
As per the question
Here
Hence frequency of the wave
Here Hertz [Hz] is the unit of frequency.
Answer:
A
Explanation:
Because Jessica pushes a 25 kilogram cart a distance of 10 meters.
It would be 22 depths inside the glass of water.
