What is intensity in black body radiation?
The intensity (or flux) at all wavelengths increases as the temperature of the blackbody increases. Although the intensity may be very low at very short or long wavelengths, at any temperature above absolute zero energy is theoretically emitted at all wavelengths (the blackbody radiation curves never reach zero).
Is black body radiation continuous?
Blackbody radiation has a characteristic, continuous frequency spectrum that experimentally depends only on the body’s temperature. In fact, we can be much more precise: A body emits radiation at a given temperature and frequency exactly as well as it absorbs the same radiation.

What will be the wavenumber of radiation having wavelength 200 nm?
The wavenumber is defined as the number of wavelengths per unit distance. Where, −νis the wavenumber. So, 200nm will be equal to 2.40×10−5 cm.
What will be the wavenumber of radiation having wavelength 5000 Angstrom?
2 x 10⁶ m⁻¹
How do you calculate the energy of radiation?
The energy associated with a single photon is given by E = h ν , where E is the energy (SI units of J), h is Planck’s constant (h = 6.626 x 10–34 J s), and ν is the frequency of the radiation (SI units of s–1 or Hertz, Hz) (see figure below).
What is the wavenumber of yellow radiation?
The wavelength of yellow light is 240×10−9m. The SI unit of wavelength is meter. The wavenumber of yellow light4.16×106m−1.
How do you find the wave number and frequency of violet radiation?
Answer: 25×10⁵m⁻¹. is wave number and 75×10¹³Hz is frequency.
- Explanation: WAVE NUMBER=RECIPROCAL OF WAVELENGTH=1/WAVELENGTH.
- ==>WAVE NUMBER=25×10⁻⁵×10¹⁰=25×10⁵m⁻¹. FREQUENCY=VELOCITY OF LIGHT/WAVELENGTH. =3×10⁸/4000A°
- =0.75×10⁸×10⁷=75×10¹³Hz. HOPE IT HELPS YOU……………………. THANK YOU.

What is the frequency of radiation whose wavelength is 2.40 10 5 cm?
Answer: The frequency of radiation is 1.25 × 10¹⁵ Hz.
What happens to the wavelength of light as the frequency increases?
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
