The energy of microwaves is less than the energy of ultraviolet light. which comparison of the energies of electromagnetic waves is correct?
a. x-rays have lower energy than gamma rays because x-rays have higher frequencies.
b. x-rays have lower energy than gamma rays because x-rays have shorter wavelengths.
c. visible light has higher energy than infrared light because visible light has longer wavelengths.
d. visible light has higher energy than infrared light because visible light has higher frequencies.

The correct answer is option D.

Explanation:

The energy(E) of the electromagnetic waves is given by:

=  frequency of the electromagnetic wave.

= wavelength of the electromagnetic wave.

The order of electromagnetic spectrum from highest frequency to lowest frequency is :

γ-rays> X-rays> UV-rays>Visible Light>Infrared>microwaves>Radio waves.

From the spectrum, the frequency of the visible light is higher than that of the infrared rays. Higher the frequency higher will be the energy of the wave.Hence option D is a correct answer.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
