Question

Compared to visible light, an electromagnetic wave that has a higher wavelength will also have ________.

Answer 1

Compared to visible light, an electromagnetic wave that has a higher wavelength will also have a lower frequency.

That's because frequency and wavelength are inversely related.

f ∝ 1/λ

When one goes up, the other goes down and vice vesa.

Answer 2

Answer: The correct answer is lower frequency.

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light.

Visible light is also an electromagnetic wave.

The relationship between wavelength and frequency of the wave follows the equation:

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = frequency of the wave

c = speed of light

$\lambda$ = wavelength of the wave

From the above relation, it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.

Thus, for higher wavelength, the electromagnetic wave will also have lower frequency.
