A high energy light will have a shorter wavelength than a low energy light. If the wavelength goes down, then the frequency goes up. When calculating energy in the equation, E=hv, frequency (v) is the variable, not the wavelength. So in the equation, if you wanted a more energy (E), you would have the frequency be large. For the frequency to be big, then the wavelength has to be low.
No, the extinction coefficient generally stays the same even as the wavelength is increased. The extinction coefficient is a property of the material being measured and does not depend on the wavelength of light.
No, not usually. Each compound has a unique absorption spectrum, and the extinction coefficient of a compound increases and decreases at different wavelengths depending on the compound. Most compounds do absorb strongly in the ultaviolet region (UV), which means that often the absorption (and extinction coefficient) often do increase a shorter wavelengths (higher energies).
No, intensity is independent of wavelength. It is dependent on the amplitude of the wave, not its frequency or wavelength.

What increase absorbance of phenol in ethanol?
Possible factors that can increase the absorbance of phenol in ethanol are: increasing the concentration of phenol in the solution, using a higher path length cuvette for measurement, and selecting a wavelength for measurement where phenol has a higher molar absorptivity coefficient.
What is the thermal expansion coefficient of ammonia?
The thermal expansion coefficient of ammonia is approximately 0.0045 K^-1 at 20 degrees Celsius. This coefficient represents how much the volume of ammonia will expand per degree of temperature increase.
What is the Coefficient of thermal expansion for oxygen?
The coefficient of thermal expansion for oxygen is approximately 0.0012 per degree Celsius. This means that for every one degree Celsius increase in temperature, oxygen will expand by 0.12% of its original volume.
Does the solubility of BaSO4 increase significantly as temperature of solution is increased?
No, the solubility of BaSO4 does not significantly increase as the temperature of the solution is increased. BaSO4 is sparingly soluble in water and its solubility is largely unaffected by changes in temperature.
What does increased Vmax suggest?
An increase in Vmax suggests an increase in the maximum rate of an enzymatic reaction, indicating an enhancement in the enzyme's catalytic activity. This could be due to factors such as increased enzyme concentration, enzyme efficiency, or substrate availability. An increased Vmax can also indicate a higher affinity between the enzyme and substrate.
What happens to the wavelength when the speed is increased and frequency stays the same?
If the speed is increased and the frequency stays the same, the wavelength will also increase. Wavelength is inversely proportional to speed for a constant frequency, so as the speed increases, the wavelength will also increase.
As the frequency of a wave of constant speed is increased does the wavelength increase or decrease?
frequency x wavelength = speedSo, if you increase frequency, the wavelength decreases, and vice versa.
How would the wavelength of a wave change if the speed of the wave increased but not the frequency?
The wavelength would increase by the same proportion.
What happenes to the wave speed as the wavelength increased?
Velocity = Frequency * Wavelength. If the wavelength increases and the frequency stays the same, then the speed of the wave will increase.
When you increase the tension on a piece of wire the speed of waves on it increase but the wavelength stays constant what happens to the frequency of the waves as the tension the wire is increased?
If the speed increased and the wavelngth stayed the same then the frequency would have to increase. Because Speed=Frequency*Wavelength Hope that helps
How would the wavelength and frequency of a wave would change if the amount of energy it carried was increased?
If the amount of energy a wave carries is increased, the frequency would increase while the wavelength decreases. This is because energy is directly proportional to frequency and inversely proportional to wavelength in a wave.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, increasing the mass of the block does not directly affect the coefficient of kinetic friction. The coefficient of kinetic friction depends on the nature of the surfaces in contact and does not change with mass.
Does diffraction increase when frequency increase?
Yes, diffraction is directly proportional to the wavelength of the wave and inversely proportional to the size of the obstacle or aperture. An increase in frequency usually corresponds to a decrease in wavelength, which can lead to increased diffraction effects if the size of the obstacle or aperture remains constant.
How would a wavelength be if the distance between the wave's crests increased?
If the distance between the wave's crests increases, the wavelength of the wave would also increase. Wavelength is the distance between two successive crests (or troughs) of a wave, so if this distance increases, the wavelength becomes longer.
What happens to the speed of a wave on a string when the frequency is doubled?
I believe that the speed will remain constant, and the new wavelength will be half of the original wavelength. Speed = (frequency) x (wavelength). This depends on the method used to increase the frequency. If the tension on the string is increased while maintaining the same length (like tuning up a guitar string), then the speed will increase, rather than the wavelength.
Predict how the wavelength of waves traveling with the same speed would change if the frequency of the waves increased?
If the frequency of the waves increased, the wavelength would decrease. This is because the speed of the waves is constant in a given medium, and the wavelength and frequency of a wave are inversely proportional to each other according to the wave equation v = Ξ»f.
How does changing the tension affect the wavelength if the frequency is constant?
If tension is increased, the wavelength of the wave will decrease. This is because the speed of the wave is directly proportional to the square root of the tension. So, if tension increases (and frequency remains constant), the speed of the wave will increase, resulting in a shorter wavelength.
