term 1 final - innovation of light n sound

innovation

is the process of creating new ideas, improving existing products or methods, or developing better solutions to make tasks easier, more efficient, and more useful in everyday life

soundproofing

is the process of reducing or blocking the transmission of sound from one area to another by using materials and techniques that absorb, reflect, or prevent sound waves from passing through

soundproofing

It helps control unwanted noise and improve sound quality in places such as recording studios, classrooms, theaters, hospitals, and homes.

acoustic foam

type of soundproof that reduces sound by absorbing sound waves that enter a room.

acoustic foam

Its porous and uneven surface traps sound energy, preventing sound waves from bouncing repeatedly on walls and creating echoes.

thick curtains

type of soundproofing that help block sound by absorbing and reducing sound vibrations that pass through windows and walls

carpets and rugs

type of soundproofing that reduce noise by absorbing sound vibrations caused by footsteps, movement, and furniture

sound amplifier

is a device that increases the strength or volume of sound by converting weak audio signals into stronger signals that can be heard more clearly by a larger audience

led

is a semiconductor device that produces light when an electric current passes through it.

light-emitting diode

what does led stand for

led

It is an energy-efficient lighting technology that uses less electricity, produces less heat, and lasts longer compared to traditional incandescent bulbs

incandescent bulbs

led is is an energy-efficient lighting technology that uses less electricity, produces less heat, and lasts longer compared to traditional ___ ___

energy-efficient, long-lasting, durable, produces less heat

what are the 4 characteristics of led

hint: ee,ll,d,plh

energy-efficient

characteristic of led that consumes less electricity while producing bright light.

long-lasting

characteristic of led that can operate for thousands of hours before needing replacement.

durable

characteristic of led that is resistant to shock and vibration compared to traditional bulbs.

produces less heat

characteristic of led that converts more electrical energy into light rather than heat.

hologram

s a three-dimensional (3D) image created using the principles of light.

hologram

can display objects with depth, allowing viewers to see different angles of the image as they move around it
