Per NCERT, energy can be transferred to an object by mechanical work, heat, light, or sound. Which of these is also a form of energy transfer mentioned in the NCERT 'Ready to Go Beyond' box?
AImaginary numbers
BRadiation (e.g. Sun's energy reaching Earth without direct contact)
CMagnetic monopoles
DReverse time travel
Answer & Solution
Correct answer: B. Radiation (e.g. Sun's energy reaching Earth without direct contact)
Per NCERT's Ready to Go Beyond box (Ch 7), radiation, conduction, electrical, sound, and nuclear are all energy-transfer modes.
