Photons of infrared radiation with wavelengths longer than those of visible light will have what kind of energy compared to that

of visisble light?
Physics
1 answer:
densk [106]3 years ago
6 0

Answer:

Infrared photons carry lower radiation energy than the visible light.

Explanation:

  • Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
  • So, we can write the energy of a single photon as follows:

       E = h*\nu (1)

  • Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
  • So, an infrared photon carries less energy that one of the visible light.

Substances that move to the stronger parts of a magnetic field are termed ______ substances; the atomic feature responsible for
Arisa [49]

Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.

<h3>What is a paramagnetic substance?</h3>

A paramagnetic substance is the substance that possess unpaired electrons that are heavily attracted in a magnetic field.

A magnetic field is defined as the field that exists around a magnet that produces a field of force.

Examples of paramagnetic substance include the following:

  • aluminum,
  • gold,
  • copper.
  • Chromium, and
  • Manganese.

These substances are known as paramagnetic substances because they possess a high number of unpaired electrons.

Other properties of a paramagnetic substance include the following:

  • They have a permanent dipole moment or permanent magnetic moment.
  • They are weakly magnetized in the direction of the magnetizing field.
  • They usually have constant relative permeability (μr) slightly greater than 1.

Therefore, Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.

A 400.0 kg storage box is held 10 m above ground by a forklift. What is its gravitational potential energy? (PE = mgh)
Kobotan [32]

Answer:

The gravitational potential energy (PE) of a particle or a system of particles is a form of energy that exists due to its position. Mathematically, it is expressed as the product of mass, gravitational acceleration, and the vertical displacement.

Explanation:

Given data:

Mass of the storage box, m = 400.0 \ kg

Height, h = 10 \ m

The gravitational potential energy of the storage box can be expressed as,

PE = mgh

PE = 400.0 \times 9.80 \times 10

PE = 39200 \ \rm J.
