To find the intensity of a bulb, you can use the formula I = P / A, where I is the intensity, P is the power of the bulb in watts, and A is the area over which the light is spread. Alternatively, you can use a light meter to measure the intensity directly in illuminance units such as lux or foot-candles.

If amplitude of the waves coming from a light bulb decreased?

The brightness decreases and light intensity gets reduced. So dim. Also, it takes a bit less air conditioning to keep the room cool. Also, it costs a bit less to operate that light bulb. Also, the bulb may last longer before it fails.

Why 100w bulb appears brighter than 40w bulb placed at same distance?

The 100W bulb emits more light energy per second than the 40W bulb, so it appears brighter due to the higher intensity of light. This increase in brightness is a result of the higher power consumption and light output of the 100W bulb compared to the 40W bulb.
