The distance between the crests.

The number of wave cycles to pass a given point per unit of time.

Electromagnetic spectrum consists of radiation over a broad range of wave lengths.

Radio waves have ................... frequency compared to ultraviolet rays.

Each color of light has its characteristic wavelength and frequency.

When sun light passes through a prism it gives the 6 colors

The ................... the wavelength the ...............the frequency and energy.

When atoms absorb energy, electrons ..............energy level

Each spectral line corresponds to ................. emitted.

Calculate the wavelength of a photon of frequency

6 ×10¹² s⁻¹

Calculate the frequency of a photon of a wavelength

4 x 10^-7 m

According to the laws of classical physics, the atomic emission spectrum of an element shouldn't be continuous.

In a photoelectric effect, if the frequency of light is low no electron would be ejected

When the electron has its lowest possible energy, the atom is in its ...................... state

Calculate the energy, in joules, of a photon of green light having a wavelength of 562 x 10^-9m?

The light emitted by an electron moving from a higher to a lower energy level has a frequency .............. proportional to the energy change of the electron.

Classical mechanics adequately describes the motions of bodies much larger than atoms, while quantum mechanics describes the motions of subatomic particles and atoms as waves.

“it is impossible to know both the velocity and the position of a particle at the same time”
