Polarisation A Level Physics Quiz

What is polarisation by transmission?

• The process of changing the color of light waves

• The process of amplifying light waves

• The process of converting light waves into sound waves

• Process of filtering out light waves oscillating in a specific direction

Explain the concept of polarisation of transverse waves.

• The speed at which transverse waves travel through a medium.

• The process of converting longitudinal waves into transverse waves.

• The orientation of the oscillations of the wave in a specific direction.

• The amplitude of the wave as it travels through a medium.

What type of waves can be polarised?

• Infrared waves and ultraviolet waves

• X-rays and gamma rays

• Light and electromagnetic waves

• Sound waves and radio waves

How does polarisation by transmission occur?

• Polarisation is the result of light waves passing through a magnifying glass

• Light waves pass through a polarising filter, allowing only light waves oscillating in a particular direction to pass through.

• Polarisation occurs when light waves reflect off a smooth surface

• Light waves pass through a prism, separating the different polarisations

What are the applications of polarisation in everyday life?

• Umbrellas, raincoats, and waterproof shoes

• Cooking pots, pans, and utensils

• Mobile phones, laptops, and tablets

• Sunglasses, LCD screens, and 3D glasses

What is the difference between polarised and unpolarised light?

• Polarised light waves vibrate in a single plane.

• Polarised light waves have random vibration patterns.

• Unpolarised light waves have a specific direction of vibration.

• Polarised light waves vibrate in multiple planes.

Explain Malus's law in the context of polarisation.

• The intensity of polarized light is inversely proportional to the angle between the transmission axis of the analyzer and the plane of polarization

• The intensity of polarized light is directly proportional to the angle between the transmission axis of the analyzer and the plane of polarization

• The intensity of polarized light transmitted through an analyzer is proportional to the square of the cosine of the angle between the transmission axis of the analyzer and the plane of polarization of the incident light.

• Malus's law only applies to unpolarized light

What are the factors affecting polarisation of light?

• Temperature, pressure, and density

• Velocity, acceleration, and force

• Angle of incidence, material, and wavelength

• Color, shape, and size

Discuss the phenomenon of polarisation in sunglasses.

• Polarisation in sunglasses helps reduce glare and improve visibility.

• Polarisation in sunglasses has no effect on reducing glare or improving visibility.

• Polarisation in sunglasses causes the lenses to fog up easily.

• Polarisation in sunglasses makes the lenses darker and harder to see through.

How does polarisation play a role in reducing glare from water surfaces?

• Polarised sunglasses block out horizontally polarised light

• Polarised sunglasses enhance glare from water surfaces

• Polarisation has no effect on reducing glare from water surfaces

• Polarised sunglasses block out vertically polarised light
