What can we infer about an astronomical object if we observe gamma or X-rays coming from it?

Something really powerful is happening there.

How are wavelength and period related to the speed of a wave?

Speed is the wavelength multiplied for frequency.

Speed is the product of wavelength and period.

Speed is the sum of wavelength and period.

Speed is the period divided by the wavelength.

What is the frequency of a wave?

The number of complete cycles in one second

The distance between two crests

The maximum amplitude of the wave

The time it takes for one complete cycle

What does the speed of light depend on?

The medium the light is traveling through

The frequency and wavelength of the light

The amplitude of the light waves

Why do electromagnetic waves not require a medium to be transmitted?

Because they are not like sound or water waves

Because they have a constant speed in a vacuum

Because they have a maximum possible speed

What does the colour of a star indicate about its temperature?

A blue star is hotter than a red star

A red star is hotter than a blue star

All stars have the same temperature regardless of their colour

The colour of a star is not related to its temperature

Why is it important to observe astronomical objects in different types of light?

To fully understand the phenomena that are going on in them

To determine their size and shape

To measure their distance from Earth

Why must telescopes observing the universe in invisible colours be placed in space?

Because the Earth's atmosphere blocks most of the invisible light

Because the Earth's atmosphere enhances the invisible light

Because space provides a clearer image due to lack of light pollution

Because it is cheaper to operate telescopes in space

Which of the following is a source of radio waves in the electromagnetic spectrum?

Electrons moving in magnetic fields

Which of the following pairs has correctly classified both types of waves?

Transverse = Gamma Rays Longitudinal = Sound Waves

Transverse = Sound Waves Longitudinal = Light Waves

Transverse = Light Waves Longitudinal = Radio Waves

Transverse = Radio Waves Longitudinal = Gamma Rays

Which of the following describes why electromagnetic waves are transverse waves and not longitudinal waves?

The particles vibrate at right angles compared to the direction of the wave.

Only electromagnetic waves can travel through a liquid medium.

All types of electromagnetic waves have compressions and rarefactions.

The elements of the medium move parallel to the direction they travel.
