Kamila [148]

Answer:

$698 \ THz$

Explanation:

Data provided as per the question below:-

Wavelength = 430.nm

The computation of the frequency of the light is shown below:-

Frequency = Velocity of light ÷ Wavelength

The Velocity of light = $= {3.0 \times 10^8 \ m/s}$

Wavelength = 430 nm = $4.30 \times 10^-^7$ m

Frequency = $\frac{3.0 \times 10^8 \ m/s}{4.30 \times 10^-^7}$

$= 6.98 \times 10^1^4 \ hz$

$= 6.98 \times 10^2 \ Thz$

= $698 \ THz$

Therefore for determining the frequency we simply applied the above formula.

The arm that was not sprayed with anything

Explanation:

The control group would be <u>the arm that was not sprayed with anything</u>.

<em>The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.</em>
