The question is incomplete, here is the complete question:
A VHF television station assigned to channel transmits its signal using radio waves with a frequency of 66.0 MHz. Calculate the wavelength of the radio waves. Round your answer to 3 significant digits.
Answer: The wavelength of the radio waves is 4.54 m
<u>Explanation:</u>
To calculate the wavelength of light, we use the equation:

where,
= wavelength of the light
c = speed of light = 
= frequency of light = 
Putting the values in above equation, we get:

Hence, the wavelength of the radio waves is 4.54 m
The answer is B, density is d=m/v

A statement from the laboratory report which best represents a conclusion for this investigation is that: D. students who spend less time studying after school get lower math grade.
<h3>What is a research?</h3>
A research is also referred to a study and it can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause), in order to determine or measure the dependent variable (the effect) and reach a logical conclusion with results.
<h3>What is an analytical research report?</h3>
An analytical research report can be defined as a well-crafted and written document that is typically used by a researcher to display a detailed analysis of the information which are obtained through a particular research method.
In this scenario, we can infer and logically deduce that a statement from the laboratory report which best represents a conclusion for this investigation is that the group of students who spend less time studying after school would get lower math grade.
