What wave is ???????

What similarity is there between ultraviolet waves and gamma waves ?

(tick all that apply)

• both longitudinal

• both transverse

• both transfer energy

• both can travel through a vacuum

What differences are there between ultraviolet waves and gamma waves ?

(tick all that apply)

• Gamma has a higher frequency than ultraviolet

• Gamma has a shorter wavelength than ultraviolet

• Gamma has a lower frequency than ultraviolet

• Gamma has a longer wavelength than ultraviolet

Which is more ionising ? Gamma or Ultraviolet ?

• Gamma

• Ultraviolet

Different materials have different densities. Light waves may change direction at the boundary between two transparent materials. What is the change in direction of a wave at such a boundary ?

__________ can cause optical illusions as the light waves appear to come from a different

position to their actual source.

Newton's Law of Motion -objects that have a resultant force acting on them

(and so their motion is changing)

Which Newton's law of motion is this ?

• first law

• second law

• third law

The acceleration of an object is directly proportional to the force acting on it, and inversely proportional to it’s mass.

1. Bigger force = bigger acceleration

2. Bigger mass = smaller acceleration

Which of Newton's law does this relate to ?

• First law

• Second law

• Third law

What is the equation to calculate wave speed ?

• Wave speed = frequency X wavelength

• Wave speed = Wavelength / frequency
