What is the wavelength of red light in vacuum that has a frequency of 4.00 × 1014 hz?

Pachacha [2.7K]

Answer: $7.5(10)^{-7} m$

Explanation:

The frequency $\nu$ of an electromagnetic wave is given by the following equation:

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

Where:

$c=3(10)^{8} m/s$ is the speed of light in vacuum

$\nu=4(10)^{14} Hz$ is the frequency of red light

$\lambda$ is the wavelength of red light

Isolating $\lambda$ :

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

$\lambda=\frac{3(10)^{8} m/s}{4(10)^{14} Hz}$

Finally:

$\lambda=7.5(10)^{-7} m$

Write two key facts about covalent bondsc

Lelechka [254]

Explanation:

Covalent bonds:

They are bonds that are formed by atoms that shares their valence electrons.
They are formed by atoms with very low electronegativity difference.
It is usually a bond between non-metals.

Covalent bonds are bonds formed when two atoms jointly shared their valence electrons in order to form a bond.

For the formation of this bond type, each of the atom requires odd or unpaired electrons.

To form a covalent bond, each of the two participating atoms would put down an unpaired electron to be used in forming a shared pair of electrons between them.

HELP ME PLEASE

Silently he crept through jagged thornbushes. Bare feet moved swiftly over hot, arid soil to the edge of a waterhole where the kudu was drinking. The great animal suddenly looked up, spiral horns curving sharply into the endless African sky. Nsue did not reach for his pouch of poisoned arrows. He had no heart for killing. This would not be the day he would change his childish boyhood name.

How does paragraph 1 contribute to Nsue’s development?

It establishes Nsue’s disappointment at not finding a suitable animal to bring to the feast.

It establishes Nsue’s apprehension of participating in the Festival of the New Moon.

It establishes Nsue’s desire to become a great storyteller like Gao, the Old One.

It establishes Nsue’s motivation to find something to take to the feast.
