Answer:

Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases because the particles of gas move faster.

What is the (a) frequency and (b) wavelength (in nm) of a source of purple light at the edge of the visible light spectrum?
stiv31 [10]

Answer: a) Frequency=666\times10^{12}Hz-789\times10^{12}Hz

b) Wavelength=380nm-450nm

Explanation: Visible light is a form of electromagnetic wave.

Wavelength is defined as the distance between two successive crests of a wave. It is represented as symbol \lambda.

Frequency is defined as the number of complete cycles happening per second. It is represented by the symbol \nu.

Wavelength and Frequency follow inverse relation,

                                              \nu=\frac{c}{\lambda}

where, c = speed of light = 3\times10^8m/s

Wavelength and frequency of a wave is usually expressed in a range.

a)  \text{Frequency of visible light}=666\times10^{12}Hz-789\times10^{12}Hz

b) \text{Wavelength of visible light}=380nm-450nm
