What is the principle behind barcode scanning?

• Barcode scanning uses sound waves to read information.

• The principle is based on magnetic fields detecting data.

• The principle behind barcode scanning is the optical reading of patterns of bars and spaces to decode information.

• Barcode scanning relies on chemical reactions to interpret codes.

How do laser barcode readers differ from traditional scanners?

• Laser barcode readers are heavier and bulkier than traditional scanners.

• Traditional scanners can read barcodes from a greater distance than laser barcode readers.

• Laser barcode readers are faster, more accurate, and can read from a distance compared to traditional scanners.

• Laser barcode readers require more maintenance than traditional scanners.

What are the advantages of using lasers in barcode reading?

• Lasers are less expensive than traditional scanners.

• Lasers can only read barcodes in perfect condition.

• Advantages of using lasers in barcode reading include high precision, ability to read damaged barcodes, longer scanning distances, and reduced sensitivity to ambient light.

• Lasers require a dark environment to function effectively.

In what ways are lasers used in metal cutting?

• Lasers are primarily used for engraving wood.

• Lasers are only effective for cutting plastics.

How does laser welding differ from traditional welding methods?

• Laser welding uses gas instead of lasers for heat.

• Traditional welding methods are always more precise than laser welding.

• Laser welding requires more manual labor than traditional methods.

• Laser welding differs from traditional welding methods by using focused laser beams for high precision and reduced heat-affected zones, while traditional methods use electric arcs or flames.

What safety precautions should be taken when using lasers in metalwork?

• Wear cotton clothing for better comfort

• Use regular glasses instead of goggles

• Wear safety goggles, use fire-resistant clothing, ensure proper ventilation, maintain safe distance, use signage, and inspect equipment regularly.

• Ignore ventilation as it is not necessary
