What is the relationship between pho Thanh energy and the color of light

AysviL [449]

Answer:

Red photons have the least amount of energy

Explanation:

The relationship between the photon energy and the color of light is given by:

$E=\frac{hc}{\lambda}$

where

E is the energy

h is the Planck constant

c is the speed of light

$\lambda$ is the wavelength (which determines the color of light)

As we see from the equation, energy and wavelength are inversely proportional: this means that the longer the wavelength, the lower the energy, and viceversa.

Among the colors in the visible light spectrum, red is the color with longest wavelength (620-750 nm) and violet is the color with shortest wavelength (380-450 nm). This means that red photons have the least amount of energy, while violet photons have the greatest amount of energy.

So the correct choice is

Red photons have the least amount of energy

In a science fiction story, a microscopic black hole is given an enormous positive charge by firing an un-neutralized ion drive

Olegator [25]

Answer: distance d = 4.73e10m

Explanation: Suppose the charge on the black hole is 5740 C which is a positive charge.

Using electric potential V formula:

V = kq / d

Where K = 9.05×10^9Nm^2/C

And e = 1.6×10^-19C

But you don't need to substitute it.

1090 V = 8.99e9N·m²/C² * 5740C /d

Make d the subject of formula

d = 4.73e10 m
