What is the frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm?
morpeh [17]

The frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm is 5.71×10^{14} s^{-1}

What is wavelength?

  • It is the length between two successive crests or troughs of any wave.

What is a frequency?

  • It is the total number of waves that pass through a fixed point in unit time.

Wavelength=525nm

The relation between wavelength and frequency

v=\frac{c}{lambda}

v=frequency

c=speed of light = 3.0×10^{8}m/sec

λ(lambda)=wavelength

substitute the value in the equation mentioned above

v=3.0×10^{8}/525×10^{-9}

=5.71×10^{14}s^{-1}

hence, the frequency of the green light emitted by a hydrogen atom with a wavelength of 525 nm is 5.71×10^{14} s^{-1}

What is the differences between amorphous solid and crystalline solid​
sp2606 [1]

Answer:

Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points.

 In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures.

What is the wavelength of an X-ray that has a frequency of 7.8 x 1017 Hz
SVEN [57.7K]

Answer:

λ = 0.38 ×10⁻⁹ m

Explanation:

Given data:

Wavelength of xray = ?

Frequency of xray = 7.8 ×10¹⁷ Hz

Solution:

Formula:

Speed of light = wavelength × frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s = λ × 7.8 ×10¹⁷ Hz

λ = 3×10⁸ m/s / 7.8 ×10¹⁷ Hz

         Hz = s⁻¹

λ = 3×10⁸ m/s / 7.8 ×10¹⁷s⁻¹

λ = 0.38 ×10⁻⁹ m
