Wave revision part 5

When light travels through two different materials it bends and changes

direction because the speed of light changes. This is called __________

• Reflection

• Refraction

When light hits an opaque object it changes direction

and bounces off. This is called _________

• Refraction

• Reflection

Light appears white or transparent, but it is actually

made up of several different colours.

Is the given statement true or false?

• True

• False

3. Red from the color spectrum has the longest wavelength.

• TRUE

• FALSE

15. As a wave, light is part of the electromagnetic waves as the visible spectrum or white light.

• TRUE

• FALSE

How does light travel

• It curves around corners
• Really slow
• In a straight line
• In circles

What angle is formed by an incoming ray and the normal line?

• Angle of reflection

• Angle of refraction

• Angle of incidence

• Angle of equivalence

Which statement correctly describes the “Law of reflection”?

• The angle of reflection is perpendicular to the normal.

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

• The angle of reflection is parallel to the angle of incidence

• Both the angle of incidence and reflection lie in different planes.

What kind of waves are light waves?

• Longitudinal waves

• Electrons

• Transverse Waves

What is the amplitude of this model wave?

• 0mm

• 5cm

• 15cm

• 10mm
