List of top Physics Questions on Dual nature of radiation and matter asked in MHT CET

Two spherical black bodies radiate the same amount of heat per second. If their temperatures are \( T_1 \) and \( T_2 \), and their radii are \( R_1 \) and \( R_2 \), respectively, find the relation between their temperatures and radii.

A photon and an electron have an equal energy ' \(\text{E}\) '. The ratio of wavelength ' \(\lambda_\text{p}\) ' of photon to that of electron ' \(\lambda_\text{e}\) ' is proportional to

An electron of mass 'm' and a photon have same energy 'E'. The ratio of de-Broglie wavelength of electron to the wavelength of photon is (c = velocity of light)

de-Broglie wavelength associated with an electron accelerated through a potential difference $V$ is $\lambda$. When the accelerating potential is increased to $4V$, the de-Broglie wavelength

A photon has wavelength $3\text{ nm}$, then its momentum and energy respectively will be $[h = 6.63 \times 10^{-34}\text{ Js}, c = 3 \times 10^8\text{ m/s}]$

The P.E. 'U' of a moving particle of mass 'm' varies with 'x'-axis as shown in figure. The deBroglie wavelength of the particle in the regions $0 \le x \le 1$ and $x > 1$ are $\lambda_1$ and $\lambda_2$ respectively. If the total energy of the particle is 'nE', then the ratio $\lambda_1 / \lambda_2$ is

What is the additional energy that should be supplied to a moving electron to reduce its de Broglie wavelength from $1\ \text{nm}$ to $0.5\ \text{nm}$?

A photon and an electron have an equal energy ' \(\text{E}\) '. The ratio of wavelength ' \(\lambda_\text{p}\) ' of photon to that of electron ' \(\lambda_\text{e}\) ' is proportional to
