Light

What is the fundamental nature of light?

• A wave

• A particle

• A liquid

• A solid

Which type of light has the shortest wavelength?

• Gamma rays

• Ultraviolet

• Infrared

• Radio waves

What is the relationship between wavelength and energy in light?

• Wavelength determines color but not energy

• Wavelength and energy are unrelated

• Shorter wavelength means higher energy

• Longer wavelength means higher energy

What happens to the color of light emitted by an object as it gets hotter?

• It becomes invisible

• It becomes redder

• It becomes bluer

• It stays the same

What is the term used to describe light with a longer wavelength?

• Bluer

• Redder

• Greener

• Violet

What determines the type of atom?

• Number of neutrons

• Number of electrons

• Number of photons

• Number of protons

How do electrons emit light?

• By staying in the same energy level

• By jumping to a lower energy level

• By jumping to a higher energy level

• By absorbing energy

What tool is used to measure the wavelength of light precisely?

• Thermometer

• Spectrometer

• Microscope

• Telescope

What does a blue shift in light indicate about an object's movement?

• The object is moving away

• The object is stationary

• The object is moving towards us

• The object is spinning

What can spectroscopy reveal about astronomical objects?

• Their size

• Their temperature and composition

• Their age

• Their gravitational pull
