The resistant wire inside a light bulb that glows to produce light is called a ...

• Conducting wire

• filament

• resistor

• magnetic field

The number of waves that move past a certain point in one second is referred to as the ... of the wave

• Wavelength

• dispersion

• speed

• frequency

Why is it better to drive a white or silver car in a hot climate?

• White and silver cars radiate light and heat better than cars of other colours.

• White and silver cars refract light and heat better than cars of other colours

• White and silver cars reflect light and heat better than cars of other colours.

• White and silver cars absorb light and heat better than cars of other colours.

What is the build-up of electrical charges on the surface of a material

• static electricity

• electrical charge

• dynamic electricity

an imaginary line on a reflective surface that forms 90 degree angle to the surface

• parallel line

• normal line

• normal

What is the correct term to describe the diagram above

• parallel circuit

• series circuit

• simple circuit diagram

• cell, wire, bulb

Look at the diagram above. Is it possible for the light bulb to flow?

• No

• Maybe

• Yes

• If only there was a switch

What is the possible negative effect of such a circuit?

• easy to learn and make

• each component connected gets equal voltage

• If one point breaks in the series circuit,the total circuit will break.

• it requires the use of a lot of wires

What is the law of the reflection of light

• the angle of reflection always the largest

• the angle of reflection is equal to the normal

• the angle of incidence is equal to the angle of reflection

the ability of a wave to change direction when it passes from one medium to another

• electric spark

• refraction

• resistor

• conductor

• radiation
