Light is used for visibility in dark or low-light conditions, helping individuals and vehicles navigate safely. Sound is used for signaling and warnings, such as alarms, sirens, or horns, to alert individuals of potential dangers or hazards. Both light and sound can be utilized in emergency situations to guide individuals to safety and provide warnings of impending threats.
Sound and light are alike when light is considered a wave. Light may also be considered a stream of particles, but in the times that it is considered a wave it obeys the same mathematical laws that sound does.
A photodetector or light sensor is used to convert light energy into electrical signals, which can then be converted into sound using a speaker or headphones. The electrical signals are amplified and converted into sound waves that we can hear.
Sound and light are both forms of energy that travel in waves. They can be reflected, refracted, and absorbed by materials. Both sound and light can be used for communication and to provide information about the environment.
Light can be used for signaling through a series of flashes or colors, Morse code, or even using specific patterns like in traffic lights. Sound can be used for communication through language, music, or alarm systems. Both light and sound can also be combined for more complex forms of communication, such as using a beacon light with a corresponding sound signal for emergency situations.
Sound is not convertible directly to light, though it can be used to attenuate electrical signals, which in turn can be used to cause variations in the output of a light source powered by those signals.

You can use light and sound to achieve so many things in everyday life. Sound is used to help people hear what others are saying while light is used in most case for vision.

'Sound and safe', usually expressed as 'safe and sound' means being very safe; being free from danger and from injury or ill-health. The phrase is frequently used when something, often a person, has been missing and then found in good health, or good condition. 'Safe' speaks for itself; 'sound' is from an old usage in English, indicating good health: 'sound in body and mind', 'sound in limb', or 'sound in wind', meaning respectively mentally and physically healthy, having arms and legs in good working order, or having good lung capacity.

A home scanner as in a copier scanner? If so than it is only a bright light used to reflect the image of what you are scanning and as so is as safe as any light.
