Red light has a wavelength of about 6.5 x 10-7m. Find its frequency. Show all work.
ozzi
For this problem we use the wave equation. It is expressed as the speed (c) is equal to the product of frequency (f) and wavelength (v).

c = v x f

We know the wavelength of the an red light which is 6.5 x 10^-7 m. Now, we solve for the wavelength of the unknown wave to see the relation between the two waves.

2.998 X 10^8 = 5.3 X 10^15 X v
v = 2.998 X 10^8 / (5.3 X 10^15) = 5.657 X 10^-8 m

Therefore, the wavelength of the unknown wave is less than the wavelength of the red light.

Active reading skills are a set of skills that help you read actively; this means skills to effectively read a text and understand it.

<h3>How to rate your reading skills?</h3>

In this case, you are asked to rate your ability to pay attention to your understanding, thoughts, and questions while reading. To do this you can:

Rate using numbers:

  1. Select a specific scale rating such as 1 to 5 or 1 10.
  2. Analyze honestly if you used this ability while reading the text.
  3. Give yourself a number. For example, if you apply this skill only sometimes while reading you can rate yourself 5 out of 10.

Rate using words:

  1. Select the types of words that you will use, the most common ones are frequency words such as always, sometimes, and never.

What is the pressure exerted by 68.0 g of nitrogen trihydride gas in a 50.0L container at 30.0 C?
Cloud [144]

Answer:

Molecular mass of NH3 = ( 14 + 3 ) = 17 g

PV =  \frac{m}{m _{r}} RT \\ P \times 50.0 \times  {10}^{ - 6}  =  \frac{68.0}{17}  \times 8.314 \times (30.0 + 273) \\ P =  \frac{68.0 \times 8.314 \times 303}{17 \times 50.0 \times  {10}^{ - 6} }  \\ P = 2.02 \times  {10}^{8}  \: Pascals
