To solve this problem, you can use the formula:
wavelength = speed of light / frequency
The speed of light is approximately 3 x 10^8 meters per second.
Step 1: Write down the given values:
Frequency = 1.258 x 10^10/s
Speed of light = 3 x 10^8 m/s
Step 2: Plug in the values into the formula:
wavelength = (3 x 10^8 m/s) / (1.258 x 10^10/s)
Step 3: Simplify the equation by dividing the numerator by the denominator:
wavelength = (3 / 1.258) x (10^8 / 10^10) m
Step 4: Simplify further by performing the calculations:
wavelength = 2.384 x (10^8 / 10^10) m
Step 5: Simplify the final calculation:
wavelength = 2.384 x 10^-2 m
Thus, the wavelength of the microwave radiation with a frequency of 1.258 x 10^10/s is approximately 2.384 x 10^-2 meters.

To solve this problem, you can use the formula that relates wavelength (λ), frequency (f), and the speed of light (c). The formula is:
c = λf
where c is the speed of light, which is approximately 3.00 × 10^8 meters per second (m/s).
To find the wavelength (λ), rearrange the formula:
λ = c / f
Now, plug in the given frequency (f = 1.258 × 10^10/s) and the speed of light (c = 3.00 × 10^8 m/s) into the formula:
λ = (3.00 × 10^8 m/s) / (1.258 × 10^10/s)
To simplify this expression, divide the numerator by the denominator:
λ ≈ 0.0238 meters
Therefore, the wavelength of microwave radiation with a frequency of 1.258 × 10^10/s is approximately 0.0238 meters or 23.8 millimeters.
