# What Is V In Mirror Formula?

V is the image, image distance, so this is image distance, and that's something we don't know in this problem. And u is the object distance, these are the letters that we usually use for mirrors, object distance.

### What is the formula of refraction by lens?

1f=(μ−1)(1R1−1R2) Hint:Consider the lens as two surfaces and not one. The rays are going from denser to rarer medium or vice versa that means a change of medium is there.

### What is Ray rays D?

D is the minimum distance between the two point object under observation. * d is the minimum distance between the two point objects for which they can be seen as separate objects through a microscope *Resolving power of a telescope : *Where D is aperture of objective of the telescope or diameter of the objective lens.

### What is prism equation?

The Prism Formula is as follows, The surface area of a prism = (2×BaseArea) +Lateral Surface Area. The volume of a prism =Base Area× Height.

### WHAT IS lens maker formula derive it for convex lens?

Derive Lens maker formula f1​=(n−1)(R1​1​−R2​1​). The lower half of the concave mirror's reflecting surface is covered with an opaque material.

### What is V in mirror formula?

V is the image, image distance, so this is image distance, and that's something we don't know in this problem. And u is the object distance, these are the letters that we usually use for mirrors, object distance.

### How do you find the angle of refraction?

How to Find Angle of Refraction

1. What is refraction?
2. Step 1: Find the refractive index of air (n1).
3. Step 2: Find the refractive index to glass (n2).
4. Step 3: Transform the equation of Snell's law so that the unknown value of the angle of refraction is on the left-side: sin r = (n1/n2)sin i.

### What is prism formula in ray optics?

It is represented as n = c/v, where c = velocity/speed of light of a certain wavelength in the air and v = velocity of light in any medium.

### What is critical angle formula?

θcrit = sin-1(nr/ni) = sin-1(1.3/1.52) = 1.064rad. θcrit = 1.064rad. 2)A ray of light strikes from a medium (n = 1.67) on a surface of separation with the air (n = 1). It calculates the limit or critical angle.

### What is M vu?

Magnification can also be related to the image distance and object distance; therefore it can also be written as: m = -v/u. Where v is the image distance and u is the object distance.

### What is the unit of refractive index?

There is no SI units for refractive index, since it is a ratio of light velocity in material vs light velocity in vacuum, all velosity units have been cancelled out and the only thing left is the number that shows the ratio. Was this answer helpful?

### What is the formula for refraction at spherical surface?

Derive the following expression for the refraction at concave spherical surface: μv−1u=μ−1R.

### What is the formula of lens formula?

Let's see how to use lens formula (1/v-1/u= 1/f) to locate images without having to draw ray diagrams.

### What is preparedness in emergency management?

Preparedness within the field of emergency management can best be defined as a state of readiness to respond to a disaster, crisis or any other type of emergency situation.

### What is use of try block?

Java try block is used to enclose the code that might throw an exception. It must be used within the method. If an exception occurs at the particular statement in the try block, the rest of the block code will not execute.

### What are the steps to solving quadratic inequalities?

To solve a quadratic inequality, you follow these steps:

1. Move all the terms to one side of the inequality sign.
2. Factor, if possible.
3. Determine all zeros (roots, or solutions).
4. Put the zeros in order on a number line.
5. Create a sign line to show where the expression in the inequality is positive or negative.

### What are the tools of capacity planning?

Here, we've evaluated five different types of capacity management tools:

• Performance monitoring.
• Trending.
• Simulation modeling.
• Analytical modeling.

### What is refractive status?

Refractive error means that the shape of your eye does not bend light correctly, resulting in a blurred image. The main types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness), presbyopia (loss of near vision with age), and astigmatism.

### What is system analyst and designer?

A systems analyst is a person who uses analysis and design techniques to solve business problems using information technology. Systems analysts may serve as change agents who identify the organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.

### Who was the first mathematician used the abbreviated notation cos?

Albert Girard also used the abbreviations 'sin', 'cos' and 'tan' for the trigonometric functions in his treatise.

### Is inorganic chemistry easy Quora?

I suggest you to focus more on inorganic because in mains, the inorganic part of chemistry is comparatively much easier than the other two. Inorganic: almost more than half of the inorganic question are going to be directly from ncert text…but you need to be thorough with the ncert text to get a decent score.
