# How to calculate lambda max?

using uv-visible spectrophotometer

concentration vs absorbance is plotted and the maximum absorbance of the drug is lambda max of the drug. then after it will decrease. still if needed clarification, refer beer lambert"s law

### What is lambda max for colorless proteins?

if the protein is colorless then it is quite tough to calculate the lambda max or absorption maxima directly (still you can check it by absorbtion maxima calculation/experiment). Otherwise, for its estimation first you have to treat it with any reagent (like folin reagent) then it will form a colored complex and then you can calculate it. For the common estimation of protein, there is a "Lowry Method" where you can calculate it on 750… Read More

### What is the reported UV lambda max of Vildagliptin drug?

The reported UV lambda max of Vildagliptin drug is 254 nm.

### What is woodwardfieser rule in uv spectroscopy?

Woodward Fieser rules are a set of emperical rules to calculate lambda max. in UV spectroscopy theoretically. They can be used to calculate the wavelength of maximum absorption of dienes and conjugated carbonyl compounds.

### What is the lambda max of pregabalin?

uv max of pregabalin are following: 1.in water 276nm 2.in methanol 210nm

### What is λmax?

Lambda max is the wavelength at which the maximum fraction of light is absorbed by a solution. Lambda (λ) is a Greek letter that scientists use as the symbol for wavelength.

### Is lambda max is chosen for all quantitative analysis?

differnce between fluoresence and phosphoresence

### What are two reasons why absorbance measurements are taken at lambda max?

to ensure maximum absorbance of light by the solution

### What is the motto of Lambda Lambda Lambda?

The motto of Lambda Lambda Lambda is 'Follow the Twelve'.

### What can you calculate by multiplying a waves frequency by its wavelength?

When you multiply a wave's frequency by its wavelenth (lambda), you get its speed or velocity.

### For a liquid to change into a solid it must lose some equal energy to heat?

when u want to change phase u should remove the heat from liquid. EX: If u want to freeze water then calculate heat to be removed from water by taking lambda... Q= (m X lambda) minus (m Cp dt) lambda at 00C

### What is the motto of Lambda Upsilon Lambda?

The motto of Lambda Upsilon Lambda is 'La Unidad Para Siempre'.

### How do you calculate wavelength when given the frequency?

Wavelength lambda and frequency f are connected by the speed c of the medium. c can be air = 343 m/s at 20 degrees Celsius (68 dgrees Fahrenheit) or c can be water at 0 dgrees = 1450 m/s. c can be light waves or c can be electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f

### What is the definition of lambda max for a particle absorbing in the uv region?

The same as for any particle absorbing electromagnetic radiation: the wavelength at which the largest amount of absorption occurs.

### What do you need to know to calculate the frequency of a wave?

wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light

### Calculate the energy of a photon of blue light that has a wavelength of 415nm?

Eh, this is really simple, open your book. E=hf=hc/lambda.

### How do you calculate hysteresis?

max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)

### How Lambda max determined for quetiapine fumarate?

by injecting the sample in to a HPLC system having PDA detector or Scan the Quetiapine Fumarate sample solution in UV range.

### What is de broglie wavelength of one photon?

p=h/lambda so lambda=h/p but E=hf=hc/lambda so lambda=hc/E hence lambda=hc/E relates wavelength (lambda) to the energy of a photon

### What is lambda divided by 4?

Just write this as lambda/4, or (1/4)lambda. You can't get a numerical value, unless you know the value of lambda.

### What two variables are needed to calculate the speed of sound?

Distance-wavelength lambda (λ) is measured in meters (m) Time- frequency is measured in Hertz (Hz)

### What is Delta Lambda Phi's motto?

Delta Lambda Phi's motto is 'Lambda Men are making their presence known.'.

### How do you calculate the speed of an electron using the de Broglie wavelength?

Speed of electron = [ planck's constant ] / [ mass x wavelength ] or v= h/ [m x lambda ]

### What fraternity did the nerds join in the 1984 film Revenge of the Nerds?

They try to join the fraternity Lambda, Lambda, Lambda (the "Tri-Lams").

### What is lamda?

Lambda is the eleventh letter of the Greek alphabet. Lambda is also used in calculus. Lambda also means wavelength in chemistry.

### What happens to wavelength and frequency if velocity increases?

We got the formula: speed of medium c = frequency f times wavelength lambda. f = c / lambda lambda = c / f If c increases, also f increases. c is proportional to f, if lambda stays constant. If c increases, also lambda increases. c is proportional to lambda, if f stays constant.

### What is the relationship between energy wavelength and frequency?

c is the speed of sound or the speed of light. You must know what you need. There is a relationship between the wavelength lambda and the frequency f. But forget the energy! c = lambda times f f is proportional to 1 / lambda. f = c / lambda lambda = c / f

### What is an eigenvector?

Given some matrix A, an eigenvector of A is a vector that, when acted on by A, will result in a scalar multiple of itself, i.e. Ax=[lambda]x, where lambda is a real scalar multiple, called an eigenvalue, and x is the eigenvector described. To find x you will normally have to find lambda first, which means solving the "characteristic equation": det(A-[lambda]I)=0, where I is the identity matrix. The derivation of the "characteristic equation" is as… Read More
