A research question that would complete the third question you need that are related to the first 2 questions which are:

  • “what type of masks help prevent fog on glasses when breathing?”
  • “does a mask’s material affect the level of fog on glasses as an effect of breathing?”

Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?

This new research question would help you find out if there is an already existing mask that could be made better.

<h3>What is a Research Question?</h3>

This refers to "a question that a research project sets out to answer". and seeks to give answers to particular phenomena.

Hence, we can see that the new research question Would be: "Are there any available masks that could prevent fog on glasses that could be improved upon"?

This new research question would help you find out if there is an already existing mask that could be made better.

What is the frequency of light for which the wavelength is 7.1 × 102 nm?
Brilliant_brown [7]

Answer:

Frequency, f=4.22\times 10^{14}\ Hz

Explanation:

Given that,

Wavelength of the light,

\lambda=7.1\times 10^2\ nm=7.1\times 10^2\times 10^{-9}\ m\\\\\lambda=7.1\times 10^{-7}\ m

We need to find the frequency of light. We know that light is an electromagnetic wave. It moves with the speed of light. So,

c=f\lambda

f is the frequency of light

f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8\ m/s}{7.1\times 10^{-7}\ m}\\\\f=4.22\times 10^{14}\ Hz

So, the frequency of light is 4.22\times 10^{14}\ Hz. Hence, this is the required solution.
