"Three short blasts" sound signal alerts others when a boat is backing up based on the boating safety rule. The short blast is a sound which has one second period, thus three short blasts mean three of this kind of sound. The sound signal is used for alerting anything surrounding the boat to avoid a collision.

If a microwave oven produces electromagnetic waves with a frequency of 2.30 ghz, what is their wavelength?
vovikov84 [41]

Answer: wavelength is 1.30 \times 10^8 nm.

The frequency of the microwave is, f = 2.30 GHz.

To Find frequency use the formula:

c=fλ

Where, c is the speed of electromagnetic wave or light. f is the frequency, and λ is the wavelength of light.

Rearranging, \lambda = \frac{c}{f}

Plug in the values,

\lambdam = \frac{3 \times 10^8 m/s}{2.30 GHz\frac{10^9 Hz}{1 GHz}}=0.130 m\frac{10^9 nm}{1 m} = 1.30 \times 10^8 nm.

The diameter in meters is found to be 3.6  * 10^-5 m.

<h3>What is the conversion factor?</h3>

When we talk about the conversion factor, we can talk about the term that we could use to express a unit in terms of another unit. We can convert from a given unit to another if we are aware of what the conversion factor is.

Now, we have been told that the diameter of the something can be given as 36.0μm and 1μm =  1 * 10^-6 m. This can be regraded as the conversion factor.

If  1μm =  1 * 10^-6 m

36.0μm =  36.0μm * 1 * 10^-6 m/1μm

= 3.6  * 10^-5 m
