A) find the wavelength of an electromagnetic wave with frequency 9.35 ghz = 9.35 109 hz (g = giga = 109), which is in the microwave range. λ = m
(b) find the speed of a sound wave in an unknown fluid medium if a frequency of 532 hz has a wavelength of 2.00 m.

(a)

(b) v = 1064 m/s                                                                

Explanation:

(a) Frequency of electromagnetic wave,

Let is the wavelength of electromagnetic wave. It can be calculated as :

(b) Frequency of medium, f = 532 Hz

Wavelength,

Let v is the speed of sound wave in an unknown fluid. Using the relation as :

v = 1064 m/s

Hence, this is the required solution.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
