<u>So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light. </u>

<u> </u>

<u>FYI,  </u>

<u>λ </u>

<u> is the Greek letter lambda , and  </u>

<u>ν </u>

<u> is the Greek letter nu (it is not the same as a v).</u>



<u>Answer:  </u>

<u>Type of Radiation Frequency Range (Hz) Wavelength Range </u>

<u>gamma-rays 1020 - 1024 < 10-12 m </u>

<u>x-rays 1017 - 1020 1 nm - 1 pm </u>

<u>ultraviolet 1015 - 1017 400 nm - 1 nm </u>

<u>visible 4 - 7.5*1014 750 nm - 400 nm </u>

<u>near-infrared 1*1014 - 4*1014 2.5 μm - 750 nm </u>

<u>infrared 1013 - 1014 25 μm - 2.5 μm </u>

<u>microwaves 3*1011 - 1013 1 mm - 25 μm </u>

<u>radio waves < 3*1011 > 1 mm</u>


<u>(Ultraviolet I believe, not sure)</u>

What would be the pH of a solution of a solution with a hydrogen ion concentration of 0.001 M?
son4ous [18]

0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.

Please help me with this question!! read the photo
pishuonlain [190]

There are 1.92 × 10^23 atoms Mo in the cylinder.

<em>Step 1</em>. Calculate the <em>mass of the cylinder </em>

Mass = 22.0 mL × (8.20 g/1 mL) = 180.4 g

<em>Step 2</em>. Calculate the<em> mass of Mo </em>

Mass of Mo = 180.4 g alloy × (17.0 g Mo/100 g alloy) = 30.67 g Mo

<em>Step 3</em>. Convert <em>grams of Mo</em> to <em>moles of Mo </em>

Moles of Mo = 30.67 g Mo × (1 mol Mo/95.95 g Mo) = 0.3196 mol Mo

<em>Step 4</em>. Convert <em>moles of M</em>o to <em>atoms of Mo </em>

Atoms of Mo = 0.3196 mol Mo × (6.022 × 10^2<em>3</em> atoms Mo)/(1 mol Mo)

= 1.92 × 10^23 atoms Mo

Sladkaya [172]

Answer:

Explanation:

1) A fulcrum is a pivot point that plays a central role (not necessarily located at the center) in a lever. The fulcrum of the attached picture has been circled (in blue).

2) The object placed on this lever's measurement tray is balanced by placing it at the center of the tray. This is the standard way of placing objects on any balance.
