Question

Gino made a table to describe parts of the electromagnetic spectrum.



What mistake did Gino make?

X-rays should have a low frequency and a long wavelength.
Infrared light should have a high frequency, not a low frequency.
Radio waves should have a very high frequency and a very short wavelength.
Ultraviolet light should have a short wavelength, not a long wavelength.

Answer 1

Answer: Ultraviolet light should have a short wavelength, not a long wavelength.

Explanation:

Relation between the frequency and wavelength if given by:

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

$\nu=\text{frequency of electromagnetic wave}$

$\lambda =\text{wavelength of an electromagnetic wave}$

$c=\text{speed of light}=3\times 10^{8} m/s$

From the above relation we can say that frequency and wavelength are inversely related to each other.

$\nu\propto\frac{1}{\lambda }$

From the Gino's table, the mistake made by her was , instead of writing low wavelength for Ultraviolet rays she wrote long. Since the ultraviolet rays have higher frequency they have low value wavelength.

Answer 2

Answer:

the correct answer is d

Explanation:

ultraviolet rays should have a short wavelenght instead of long wavelength
