Solution: Let’s write down what is given in the question: Wave velocity (v) = 1.50 m/s. The wavelength of the wave is (λ) =2.0 m. Furthermore, we have to rearrange the formula for calculating the answer: λ = v f → f = v λ. f = 1.50m/s 2.00m. f = 0.75 waves/s. So, the frequency of the wave is 0.75 waves per second.
Speed = Frequency x Wavelength. Furthermore, wavelength = (Speed of the wave)/ (Frequency of the wave) As mentioned above, the representation of all the quantities is by a symbol. The symbolic representation of the formula above is as: C = f × λ. In terms of wavelength to frequency, the expression of the formula is as: λ = cf.
In physics, the wavelength is the period of a periodic wave. It is the distance over which the wave’s shape rehashes. It is the distance between consecutive corresponding of the same phase. For example, two crests, troughs, or zero-crossings. It is an attribute of both travelling and standing waves.
In order to calculate the frequency of the photon particle, we will use the formulas: λ = c f. Rearrangingn the formula, f = c λ. = 3×108 500×10−9. = 6 ×1014Hz. Q.2: For a light ray which have the wavelength equal to 200 nm, calculate the frequency of the ray. Solution: As given, in the problem,
Wavelength range is from 700-400 nm. Ultraviolet Rays. Ultraviolet rays have wavelengths ranging from 4 x 10-7 m (400 nm) to 6 x 10-10 m (0.6 nm). These rays can have harmful effects on humans if exposed to in large quantities. Ordinary glass absorbs UV rays. In other words, sit behind a glass window and avoid suntans and sunburns.
The de Broglie wavelength of the photon can be computed using the formula: λ = h p. = 6.63×10−34 1.50×10−27. = 4.42 ×10−7. = 442 ×10−9. = 442 Nano meter. Therefore, the de Broglie wavelength of the photon will be 442 nm. This wavelength will be in the blue-violet part of the visible light spectrum. Q. 2: The de Broglie wavelength ...
Rydberg formula is formula to compute wavelength of light. When electron changes from one atomic orbit to another, energy of electron changes with high energy to a lower energy state, then photon of light is created. When electron moves from low energy to higher energy state, photon of light is absorbed by the atom.
Calculate the de Broglie wavelength associated with a helium atom in a helium gas sample at 30 K and 1 a t m pressure.(Take h = 6 × 10 − 34, N A = 6 × 10 23 and Boltzman constant 1.5 × 10 − 23 in their standard unit)
Define wavelength of a wave. The distance between two consecutive compressions (C) or two consecutive rarefactions (R) is called the wavelength. The wavelength is usually represented by λ (Greek letter lambda). Its SI unit is metre (m).
The ionization energy of sodium will be equal to the energy possessed by the radiation of wavelength 242 nm. It is E = h c λ = 6.626 × 10 − 34 J s × 3 × 10 8 242 × 10 − 9 m = 8.21 × 10 − 19 J .
