Answer:
divide 15 from A
Step-by-step explanation:
The wavelength for radio waves with frequency 3 × 10⁹ Hz is 0.1 m.
<h3>What's the relation between frequency and wavelength of electromagnetic waves?</h3>
- For electromagnetic waves travelling in vaccum, the product of frequency and wavelength is the speed of light in vaccum.
- Mathematically, frequency × wavelength = 3×10⁸ m/s (which is speed of light)
- So, wavelength= 3×10⁸/ frequency
<h3>What's the wavelength of radio wave with frequency 3×10⁹ Hz ?</h3>
Wavelength of the radio wave= 3×10⁸/3×10⁹ = 0.1 m
Thus, we can conclude that the wavelength of the radio wave with frequency of 3 × 10⁹ Hz is 0.1 m.

Okay, so here is a small lesson on rounding. When you round you MUST know the place value of each number. Ones, tens, hundreds, thousands, millions.
So, when we look at this number what do we have in the ones place --there is a 0 -- in the tens place we have a 9 and in the the thousands place we have 5. to round this number look at the tens place. if the number is greater than 5 you round 73590 to 73600, if it is 4 and lower it stays the same and the numbers behind change to zero--> like so 73500. But for this problem it would round up to 73600.
It is called a long ton which is 2,240 pounds where a ton is 2,000 pounds.\
