Since you did not enumerate the features to choose from, I'll just give you a brief information about acidic water.
>Acidic water<span> has a pH below 7 or less than 7.0.
</span>> Acidic water can dissolve a limestone rock.
> The <span>land features which are formed in limestone by reaction with acid water are the stalactites and the stalagmites.</span>
Electricity<span> is </span>measured<span> in </span>units<span> of power called Watts</span>
Wave speed is 8 m/s
Explanation:
- Wave speed or speed of the wave is given by the formula
v = distance traveled by the wave/time
- Here, distance traveled = 16 m and time = 2 s
⇒ Wave speed = 16/2 = 8 m/s
1.
The wavelength of microwaves are longer than that of visible light . Please see the attached image to understand how visible light and microwaves differ in terms of wavelength. You will find that Visible light wavelength is in the range of 400-700 nanometers, or around
m, while microwave's wavelength is around
m.
2. As seen in the above explanation,visible light has a wavelength of around
m while microwaves have a wavelength of around
m. That means microwaves are
times the wavelength of visible light. That means
they differ in wavelength by 3-4 orders of magnitude
