How do you calculate for the wavelength?

How do you calculate for the constant speed of light?

How do you calculate for the frequency?

In the calculation, we arrived at 5.0x10^2 meters for the frequency of the given photon. In what electromagnetic wave does the value belong to?

It is the electromagnetic radiation whose wavelength and color depend on the temperature of the object. 

This theory states that as you increase the temperature, there will be emission of radiation depending on the body. 

In the blackbody radiation, as the wavelength decreases, the intensity will increase. However, there are points where intensity decrease.

Blackbody absorbs all radiation

In te black body radiation, classical physics could not explain the sharp decrease in the intensity of radiation as observed in the blackbody problem. This is called UV Catastrophe (Ultraviolet Catastrophe) wherein the wavelength is below 400 nanometer. Who proposed the solution to the blackbody problem?

Max Planck proposed that ENERGY IS _____________ rather than continuous. He proposed that the energy of EM is like matter and is discontinuous.

Max Planck's Solution to the Blackbody Problem:

Energy of EMR is quantized; for each temperature, there is a maximum intensity of radiation that is emitted in a blackbody object versus wavelength and a shift in the position of the maximum to lower wavelength (higher frequency) with increasing temperature. 

Matter could also absorb of emit energy only in the whole number multiples of the quantity. So, ΔE = nhv (where n is an integer)

Quantized manner, with steps: continuous or discontinuous?

It states that electrons are emitted from the surface of a metal when light strikes it. 

Classical physics predicted that the number of electrons and kinetic energy should depend only on the intensity of light and not the frequency.

It was found out in the photoelectric effect that the experimental results showed that each metal has a characteristics __________ frequencies. If below the ___________, no emission of electrons. If above the ___________, the number of electrons emitted is proportional to the intensity of light, and their KEα (alpha) v. 

PHOTOELECTRIC EFFECT: Metals have characteristics threshold frequencies. 

The photoelectric effect problem was solved by who?

Each  metal has a particular electrostatic attraction for its electrons. This attraction must be overcome before an electron can be emitted from the natural surface.
