An electromagnetic wave travels in a vacuum. The wavelength of the wave is tripled. How is this accomplished?
love history [14]

Answer:

The wavelength of the wave is tripled this can be done by reducing the frequency of the wave by factor of three.

Explanation :

The relation between the wavelength & frequency of a wave is given by

C = ν λ

Where

C - it is the velocity of light in vacuum.

ν - frequency of the wave.

λ - wavelength of the wave.

So we find that wavelength of a wave varies inversely with the frequency of a wave i.e. ν ∝ 1/λ.

A woman drives 200 miles west and then turns south and drives 375 miles. Her trip takes her 11.75 hrs. What is the woman's avera
FromTheMoon [43]

Answer:

The woman's average velocity during the trip is 36.2 miles/hour.

Explanation:

Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.

i.e velocity = \frac{displacement}{time}

From the given question,

Displacement = \sqrt{200^{2} + 375^{2}  }

                       = \sqrt{40000+140625}

                       = \sqrt{180625}

                       = 425

The displacement of woman is 425 miles.

velocity = \frac{425}{11.75}

             = 36.1702 miles/hour

The woman's average velocity during the trip is 36.2 miles/hour.
