Observation of Solar Eclipse
The strong sunlight would cause blindness if an observer looks at the
Sun directly. A safe method to observe the solar eclipse is to project the solar
eclipse image through a pin-hole device onto a white cardboard and look at the
projection (see Figure 1). A telescope can be used to replace the pin-hole
device to produce clearer images but the observer must ensure that he/she looks
at the cardboard only.
