What is the average kinetic energy in joules of hydrogen atoms on the 5500ºc surface of the sun?

Masteriza [31]3 years ago

The kinetic energy is related to the temperature of the system using this formula:

E = (3/2)kT
where
k is the Boltzmann's constant (1.38×10⁻²³ J/K)

The temperature in K is:
T = 5500 +273 = 5773 K

E = (3/2)(1.38×10⁻²³ J/K)(5773 K)
<em>E = 1.195×10⁻¹⁹ J</em>

Infrared radiation has frequencies from 3.0×1011 to 3.0×1014 Hz, whereas the frequency region for microwave radiation is 3.0×108
igor_vitrenko [27]

Answer:

1. The speed of infrared radiation is the same as microwave radiation.

2. The wavelength of infrared radiation is lower than microwave radiation.

Explanation:

1. The speed of infrared radiation is the same as microwave radiation. This is because both infrared radiation and microwave radiation are electromagnetic waves and all electromagnetic waves move at the same speed, the speed of light.

2. Frequency and wavelength has an inverse relationship. This means that the higher the frequency, the lower the wavelength.

Since the frequency range of infrared waves is higher than that of microwaves, the wavelength range of infrared waves is lower than that of microwaves.

We can prove this by using the maximum frequency value of each wave to calculate their corresponding wavelengths.

Speed of light, c, is given as:

c = λf

Where λ is wavelength and f is frequency.

Wavelength is therefore:

λ = c/f

For infrared wave, the maximum frequency is 3 * 10^14 Hz, hence the corresponding wavelength is:

λ = (3 * 10^8) / (3 * 10^14)

λ = 10^(-6) m

For microwave, the maximum frequency is 3 * 10^11 Hz, hence the corresponding wavelength is:

λ = (3 * 10^8) / (3 * 10^11)

λ = 10^(-3) m

Hence, the wavelength of infrared waves is lower than the wavelength of microwaves.

The fraction of the total radiation that is reflected by any surface is called its _____.
Vadim26 [7]

Answer: D. Albedo

Explanation:

The proportion of total light incident on surface that is reflected back is called its albedo. These are typical features of an astronomical body. It is a dimension less quantity and its value ranges from 0 to 1. Light surfaces reflect larger amount of light than dark surfaces. This feature can be clearly seen on planet Mars and the Moon.

Thus, the fraction of the total radiation that is reflected by any surface is called its <u>Albedo.</u>
