Correct Answer: Doppler weather RADAR
Solution : The correct answer is Doppler weather RADAR.
When an electromagnetic pulse impacts an item, such as a raindrop or a snowflake, the wave bounces back to the radar, providing meteorologists with data to analyse. Meteorologists can utilise this data to pinpoint particular locations where risky weather conditions exist. As a result, radar may be a valuable weapon in a meteorologist's inventory for assisting in the protection of life and property.
