In a room with no windows, Keiji and Olumide are standing at opposite ends. If Keiji lights a candle, will Olumide be able to see the flame immediately, and how will this affect the temperature Olumide feels? Respond very briefly.
Olumide will be able to see the candle flame as soon as Keiji lights it because light travels instantly within human perception across typical room distances. However, the change in temperature will not be felt immediately by Olumide. Heat from the candle will take time to warm the air around it and even longer to spread across the room. Since heat transfer through air occurs at a finite speed, Olumide will only perceive an increase in temperature after the warmed air diffuses across the room or through convection currents, which is a slower process than the propagation of light.
