The microwaves in a certain microwave oven have a wavelength of 12.2 cm.

**Part A**
How wide must this oven be so that it will contain five antinodal planes of the electric field along its width in the standing wave pattern?
Express your answer in centimeters.

L = ____ cm

**Part B**
What is the frequency of these microwaves?
Express your answer in hertz.

f = ____ Hz

**Part C**
Suppose a manufacturing error occurred and the oven was made 6.0 cm longer than specified in part A. In this case, what would have to be the frequency of the microwaves for there still to be five antinodal planes of the electric field along the width of the oven?
Express your answer in hertz.

f = ____ Hz

Answer :

The width of an oven needed to contain five antinodal planes of an electric field in a standing wave pattern can be determined by using a formula.

The formula is: Width=(n * λ)/2, where n is the number of antinodal planes and λ is the wavelength. In this case, n is 5 and the wavelength is given as 12.2 cm. So, the width of the oven is:

Width = (5 * 12.2 cm) / 2 = 30.5 cm

To calculate the width of the oven, we can use the formula Width = (n * λ) / 2, where n represents the number of anti nodal planes and λ represents the wavelength. In this problem, we are given that the wavelength of the microwaves is 12.2 cm. Since we want to have five antinodal planes, we can substitute n with 5 in the formula. Using the given values, we can calculate the width of the oven as follows:

Width = (5 * 12.2 cm) / 2

Width = 30.5 cm

Therefore, the width of the oven should be 30.5 cm in order to contain five antinodal planes of the electric field in the standing wave pattern.

The width of the oven needed to contain five antinodal planes of the electric field in the standing wave pattern is 30.5 cm.
