Snells Law, Refraction And Reflection Of Ultrasonic Waves

Like light, when an incident ultrasonic wave encounters an interface to an adjacent material of a different velocity, at an angle other than normal to the surface, then both reflected and refracted waves are produced.

Understanding refraction and how ultrasonic energy is refracted is especially important when using angle probes or the immersion technique. It is also the foundation formula behind the calculations used to determine a materials first and second critical angles.

First Critical Angle

Before the angle of incidence reaches the first critical angle, both longitudinal and shear waves exist in the part being inspected. The first critical angle is said to have been reached when the longitudinal wave no longer exists within the part, that is, when the longitudinal wave is refracted to greater or equal than 90, leaving only a shear wave remaining in the part.

Second Critical Angle

The second critical angle occurs when the angle of incidence is at such an angle that the remaing shear wave within the part is refracted out of the part. At this angle, when the refracted shear wave is at 90 a surface wave is created on the part surface

Formula

The relationship between the angle of the incident and refracted sound waves is descibed by the following formula:

Sin(A1)/V1 = Sin(A2)/V2

Where

A1 = The incident sound wave angle in degrees
V1 = The acoustic velocity of the incident material in metres per second
A2 = The refracted sound wave angle in degrees
V2 = The acoustic velocity of the refracted material in metres per second

By simple arrangment the formula may be changed to find any one of the values, provided that the other three unknown values are supplied.

E.g. To find the refracted angle, given the incident angle and velocity and the refracted material velocity the equation is rearranged as below:

V2 * (Sin(A1)/V1) = Sin(A2)

Getting the inverse of the answer, that is the inverse of Sin(A2) will return the angle in degrees of the refracted angle.

GM Sued Under Lemon Law

While Toyota is definitely taking the brunt of recalls lately, other vehicle manufacturers have troubles of their own: GM is currently being sued over a 2009 Chevrolet. The owner of the Chevrolet claims he experienced repeated problems that caused him to fear for his safety.

This is not the first time GM has been sued for safety issues – in 2009 a wrongful death suit was filed against them for defective seat belts. 2009 also saw a recall of almost 1.5 million mid- and full-size Buick, Chevrolet, Oldsmobile and Pontiac vehicles because of an engine oil leak problem that could pose a fire risk.

This kind of defect in a vehicle is precisely what the lemon law is about. It protects consumers from the harm or loss caused by purchasing a defective vehicle. Who has what rights and what duties in lemon law matters? It seems clear. The consumer has the duty to present the vehicle to the manufacturer or its representative, the dealership, in order that they are able to diagnose the defect and repair it. Along with the duty, the consumer has a right to expect the dealership to repair the vehicle honestly and expeditiously.

What are the rights of the manufacturer? Simply put, they have the right to expect that the consumer will present their defective vehicle at an authorized dealer for repair in a timely manner, and that the consumer properly maintain the vehicle. The manufacturer should have no other expectation. They should not expect a consumer to perfectly describe the defect they are experiencing or any other limiting requirement.

Of the thousands of lemon law clients we have spoken with, it is extremely rare that a manufacturer makes a legitimate offer to buy back or replace a defective vehicle. In each of these cases no hint of awareness of their affirmative duty was present.

Not all manufacturers or dealerships are the same. Some, certainly not enough, really do have the consumers best interests at heart.

If however you find yourself with a defective vehicle and a manufacturer who is not ready to step up and replace or refund as they should, find yourself an experienced lemon law attorney. Do your homework. Look at their record. See what others who have used their services have to say.

Be certain they offer you a free case evaluation without delay. Never be afraid to ask hard questions. Its important and it can determine the outcome of your lemon law case.

Mississippi Car Salvage Laws

Auto salvage laws were implemented as a measure against the operation of unsafe vehicles on the roadways and Mississippi car salvage laws are no different.

Salvage Title

All trucks and cars operated in the state of Mississippi should have a title under code 162 of the Mississippi Department of Public Safety (DPS).

Additionally, be sure to provide information relating to the type of damage the car suffered.

Motor Vehicle Inspection

Section 63-1309 of Code 162 requires that salvage cars must be inspected at any authorized auto inspection service station in Mississippi before the car is allowed on the states roads. Ensure you take proof that the car has been repaired when you go to have the car inspected as well as photos of the car before the repair was done.

Flood/Hail Damage

Mississippis Salvage Inspection Unit has a Bureau of Investigation, which asks that insurance companies make contact with the DPS before they take over the ownership of any car declared salvage. In addition, insurance companies are also required to title the salvage car in the companys name beforehand. Four photos showing the state of the car before repair is also required in this case. The title for cars suffering flood damage will be marked Flood Brand but for those with hail damage, the title will remain unmarked.

Selling the Car

The DPS Bureau of Investigations require that you inform the buyer that the purchase is a salvage car as this will stay a permanent part of the cars title history. This requirement will apply regardless of how the vehicle was damaged.
