The frequency of light having a wavelength of 425nm will be 70588 ×
.
The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.
A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places in the consecutive cycles.
Given data:
wavelength = 425nm = 
Frequency can be calculated by using the formula;
Frequency = speed of light / wavelength
Frequency = 3 ×
/ 425 ×
= 7,0588 ×
.
Therefore, the frequency of light having a wavelength of 425nm will be 70588 ×
.

It also depends on what we use to make the energy in the power plants. Many use uranium which is non renewable. A better alternative would be wind or solar as it is always around. Hope this helps.
Answer:
54.72 g
Explanation:
Mass = ?
Volume = 5.61 L
Pressure = 5.66 atm
Temperature = 311 K
The relationship between these equations is given by the ideal gas equation;
PV = nRT
where R = gas constant = 0.0821 atm L K-1 mol-1
n = PV / RT
n = 5.66 * 5.61 / (0.0821 * 311 )
n = 1.2436 mol
Number of moles = Mass / Molar mass
Mass = Number of moles * Molar mass = 1.2436 * 44 = 54.72 g
