What is the primary characteristic of a black body in terms of radiation?

• It reflects all incoming radiation

• It absorbs all incoming radiation

• It only emits infrared radiation

• It only absorbs ultraviolet radiation

Which of the following best describes the emission pattern of hotter objects according to black body radiation curves?

• They emit more radiation at longer wavelengths

• They emit equal radiation at all wavelengths

• They emit more radiation at shorter wavelengths

• They do not emit any radiation

What type of spectra is produced by hot gases or plasma?

• Continuous spectra

• Absorption spectra

• Emission spectra

• Reflection spectra

Which of the following is a characteristic of continuous spectra?

• Light is emitted at specific wavelengths

• Light is absorbed at specific wavelengths

• Light is spread across all wavelengths without gaps

• Light is only emitted in the visible spectrum

What does the light-gathering power of a telescope primarily affect?

• The ability to observe during daytime

• The telescope's resistance to atmospheric interference

• The ability to observe faint and distant objects

• The telescope's magnification power

Which type of telescope is best suited for observing heat emitted by cool stars and star-forming regions?

• Optical telescopes

• Radio telescopes

• Infrared telescopes

• Gravitational wave detectors

What is a significant advantage of radio telescopes in astronomical observations?

• They can observe objects regardless of time of day or weather

• They are compact and easy to transport

• They are immune to man-made radio interference

• They provide high-resolution images in the visible spectrum

Which space-based telescope is designed to observe the universe primarily in infrared light?

• Hubble Space Telescope

• James Webb Space Telescope

• Spitzer Space Telescope

• Chandra X-ray Observatory

What is a major limitation of ground-based infrared telescopes?

• They cannot detect faint infrared signals

• They are too small to gather sufficient light

• Much of the infrared spectrum is absorbed by Earth's atmosphere

• They can only operate during nighttime
