What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73x10^20 Hz?

Chemistry
1 answer:
Amanda [17]2 years ago
8 0

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

Speed of Light = Wavelength times Frequency

  • c = λν
  • c = 3.0 × 10⁸ m/s

Explanation:

<u>Step 1: Define</u>

ν  = 2.73 × 10²⁰ Hz

<u>Step 2: Find wavelength</u>

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

<u>Step 3: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules.</em>

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m

2. Describe How are the two forms of energy<br> carried by waves and matter related?
Kazeer [188]

Answer:

the energy of matter implies the motion of masses and the energy of the wave has no moving masses

The energy of the particles (matter) is the ability to do some work, therefore the energy can be of motion in the form of kinetic energy or in a configuration of the system called potential energy, the sum of these two energy is constant .

The wave is formed by a disturbance of the medium by matter, therefore for the formation of the wave matter supply energy, for example: in the form of movement, in the form of fluctuation of electric or magnetic field, etc.

The waves after being formed can move away from the matter that formed them, transporting the energy that alternately has kinetic and potential energy, but the total energy is constant.

Therefore the energy in matter is due to the movement of the same and the energy in the wave does not require the movement of matter, so it is a more efficient way of doing work.

In conclusion, the energy of matter implies the movement of masses and the energy of the wave has no moving masses.

A wave has 9.2 x 10-22 ) of energy. What is its wavelength?
blagie [28]

Answer:

\lambda=2.2x10^{-4}m

Explanation:

Hello!

In this case, since the relationship between energy and wavelength is defined via the speed of light and the Planck's constant as shown below:

e=\frac{c*h}{\lambda}

Since c stands for the speed of light and h for the so-called Planck's constant, we can compute the wavelength as follows:

\lambda=\frac{c*h}{e}=\frac{3.0x10^8m/s*6.626x10^{-34}J*s}{9.2x10^{-22}J}\\\\\lambda=2.2x10^{-4}m

Best regards!

Which one does Temperature measure
Effectus [21]

Answer:

B. how fast the particles are moving

Explanation:

Temperature measures the average kinetic energy of system as result of the thermal - heat energy present in the reaction or a body.

Often times, temperature is the degree of hotness or coldness of a body and this translates to an increase or decrease in the molecular speed.

  • Number of particles in a body is the mass of the body.
  • How tightly packed the particles are corresponds to the density of the body.

chemistry A basketball is inflated to a pressure of 1.10 atm in a 28.0°C garage. What is the pressure of the basketball outside
butalik [34]

Answer : The final pressure of the basketball is, 0.990 atm

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T

or,

\frac{P_1}{P_2}=\frac{T_1}{T_2}

where,

P_1 = initial pressure = 1.10 atm

P_2 = final pressure = ?

T_1 = initial temperature = 28.0^oC=273+28.0=301.0K

T_2 = initial temperature = -2.00^oC=273+(-2.00)=271.0K

Now put all the given values in the above equation, we get:

\frac{1.10atm}{P_2}=\frac{301.0K}{271.0K}

P_2=0.990atm

Thus, the final pressure of the basketball is, 0.990 atm
