Which of the measurements would be the most helpful in determining the wavelength
In-s [12.5K]
So we want to know what do we need to measure to determine the wavelength of the wave on the image. A wavelength is the distance between peaks of the wave. More generally, the distance on which the wave shape repeats. So on the image we need to measure X to determine the wavelength. So the correct answer is X.

Enter your answer in scientific notation
Oxana [17]

It takes 1.7 x 10 ^4 for light from the sun to reach the comet.

<h3>How do scientific notations work?</h3>

The number is written in the form  a \times 10^b where we have 1 \leq a < 10

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of the power of 10 is known, which helps in the easy comparison of quantities differing by a large value.

A comet is about  5.1 \times 10 ^9 km from the sun.

Light travels at about 3.0 \times 10 ^5 km per second.

\dfrac{5.1 \times 10 ^9}{3.0 \times 10 ^5}

= 1.7 \times 10 ^4

Hence, It takes 1.7 x 10 ^4 for light from the sun to reach the comet.
