If you can help with this problem, I would so appreciate it. If I can understand, I think I can do the rest of them. Here is the problem and the answer. How do I work through to the answer? A certain radio wave has a frequency of 1.03 MHz. What is the wavelength? Answer 2.91 "box" 10 "superscript 2" m (what does the box symbol stand for?) Thank you, thank you!!!

If you can help with this problem, I would so appreciate it. If I can understand, I think I can do the rest of them. Here is the problem and the answer. How do I work through to the answer? A certain radio wave has a frequency of 1.03 MHz. What is the wavelength? Answer 2.91 "box" 10 "superscript 2" m (what does the box symbol stand for?) Thank you, thank you!!!

Answer 1

For a "radio" or light wave, travelling in a vacuum or air, the speed of the wave is

c = 3.00*10^8 m/s

The wavelength is given by the formula

wavelength = c/f
where f is the frequency.

In your case,

wavelength = 3.00*10^8/1.03*10^6
= 291 m
This can also be written

2.91*10^2 m

I have no clue what the "box 10" refers to. They are trying to say 2.91 times ten-squared. The "box" may be the multiplication symbol, for which I used *.

Answer 2

To find the wavelength of a radio wave, you can use the formula:

wavelength = speed of light / frequency

The speed of light is a constant value, which is approximately 3.00 x 10^8 meters per second.

In this case, the frequency is given as 1.03 MHz, which is equivalent to 1.03 x 10^6 Hz.

Now, let's plug these values into the formula to find the wavelength:

wavelength = (3.00 x 10^8 m/s) / (1.03 x 10^6 Hz)

Next, let's simplify the expression:

wavelength = 2.91 x 10^2 meters

The "box" symbol is typically used to represent multiplication in scientific notation. So, the answer is 2.91 x 10^2 meters, which means the wavelength is 291 meters.

I hope this helps! Let me know if you have any further questions.

Answer 3

To find the wavelength of a radio wave, you can use the equation:

wavelength = speed of light / frequency

where the speed of light is approximately 3.00 x 10^8 meters per second.

So, to solve the problem using this equation:

1. Convert the frequency given, 1.03 MHz, to the SI unit of Hertz (Hz). Since 1 MHz = 1 million Hz, the frequency becomes 1.03 x 10^6 Hz.

2. Substitute the values into the equation:

wavelength = (3.00 x 10^8 m/s) / (1.03 x 10^6 Hz)

3. Simplify the equation by dividing the speed of light by the frequency:

wavelength = 2.91 x 10^2 m

In scientific notation, this answer can be written as 2.91 × 10^2 m, which means 2.91 times 10 raised to the power of 2 meters. The "box" symbol that you mentioned is typically used to indicate multiplication, so in this case, it represents multiplying 2.91 by 10^2.

Therefore, the answer to the problem is 2.91 × 10^2 m or 291 m.
