Question

Identify the form of electromagnetic radiation in each pair that has the greater energy:
a. Green light or yellow light.
b. Microwaves or blue light.

Short answer

(a) Green light has more energy than yellow light.

(b) Microwaves has more energy than blue light.

Step-by-step solution

Part(a) Step1 : Given information.

We have been given that,

Green light , yellow light

We need to find which electromagnetic radiation has more energy.

Part(a) Step2 : Simplify.

Green light has more energy than yellow light .

Since, wavelength of green light is less than that of yellow light ,therefore energy is more.

$Energy$ $\propto$$\frac{1}{wavelength}$

Part(b) Step1 : Given information.

We have been given that,

microwaves, blue light

We need to find which electromagnetic radiation has more energy.

Part(b) Step2 : Simplify.

Microwaves has more energy than blue light.

Wavelength of microwaves is less than that of blue light, hence poses more energy. It is dangerous for human skin.
