A certain microwave has a
wavelength of 0.032 meters. Calculate the frequency of this
microwave

Microwave has the  wavelength of 0.032 meters so, the frequency is and this will be determined by using the frequency formula.

Given :

Wavelength = 0.032 m

The Formula of Frequency can be used to determine the wavelength of the microwave:

  --- (1)

where, is the speed of light and w is the wavelength.

Now, put the values of speed of light (c) and wavelength (w) in equation (1).

For more information, refer to the link given below:

Explanation:

Frequency is mathematically defined as the quotient of speed divided by wavelength.

where

v-is the speed of light

-w is wavelength.

Given the speed of the wave  as and the wavelength , we substitute these values in the Frequency function to solve for frequency:

Hence, the wave's frequency is

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
